How many hours drive is 80km?
So if the car is travelling at a constant 80 km/ hour speed at a fixed distance of 80km. It will take just 1 hour to travel 80km.
What is the average speed of a car that travels?
The average trip distance globally is 15 Kilometers / 9.3 miles. The average speed globally is 30 km/h (or) 18.6 mph.
What is the average speed in kilometers per hour?
For example, if the total distance travelled was 250 miles and the time it took was 5 hours, then the average speed was 250 / 5 = 50 miles per hour (mph). If the distance was 200 kilometers and it took 4 hours to cover it, then the speed was 200 / 4 = 50 km/h (kilometers per hour).
What is the distance traveled by a car which traveled at a speed of 80 km/hr for 3 hours and 30 minutes?
240 kms
What is the speed of a car that travels 700 km in 3 hours and 30 minutes?
Answer. Total time=3 hour 30 mint= 3 hour mint. =3.5 mint. Speed of the car= =200 km/hour.
What will be the distance Travelled by a car after 90 minutes?
Distance covered in 90 minutes = 32 × 90 = 2880 m.
How many miles is 2 hours?
If you go 70 miles in 1 hour, then you’ll go 140 miles in 2 hours, as long as your speed is constantly 70 mph.
How do you convert speed and distance to time?
To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
What is formula for calculating speed?
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.
How fast are we going?
Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour. As schoolchildren, we learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour.
What was my average speed?
What is the formula to calculate average speed? The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed, add the two together, and divide by 2.
What was Usain Bolt’s top speed?
44.72km/h
How fast did I walk in mph?
What Is the Average Walking Speed of an Adult? The average walking speed of a human is 3 to 4 miles per hour, or 1 mile every 15 to 20 minutes. How fast you walk can be used as an indicator of overall health.
How do I work out average speed?
To get average speed, s , divide total distance by elapsed time: Dt. To get elapsed time, t , divide total distance by speed: Ds. To get distance, D , multiply speed times the amount of time: s × t.
Can you get a ticket from an average speed camera?
What is a linked average speed camera? If the vehicle’s average speed is higher than the posted speed limit then the driver will be booked and fined. In NSW, heavy vehicle drivers will receive an extra point deducted from their licence as well as the demerit points for the speed they’ve exceeded the limit by.
How do I calculate the average?
How to Calculate Average. The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. For example, suppose we want the average of 24 , 55 , 17 , 87 and 100 . Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6 .
How do you work out average speed with 2 speeds?
Average Speed = (a + b)/2 Applicable when one travels at speed a for half the time and speed b for other half of the time. In this case, average speed is the arithmetic mean of the two speeds.
How do you find average speed without time?
Without time, speed has no meaning, and the equation has a “divide by zero” error. You can do it if the body is uniformly accelerated. Just add the initial speed to the final speed and divide the sum by two. The result is average speed.
How do you find the average speed of a round trip?
FINDING THE AVERAGE SPEED IN ROUND TRIP
- Finding average speed :
- If a person travels from A to B at some speed, say “x” miles per hour.
- Then, the formula is to find the average speed for the whole journey is given below.
- = 2xy / (x + y)
- For example, a car traveling from one city to another will rarely move at a constant speed.
Which is the suitable average for calculating average speed of a journey?
The correct answer is (d) Harmonic mean. It is the best method for finding the average speed of a journey. Explanation: Average speed can be determined by dividing the total distance by the total time, which is the harmonic mean of the speeds.
What is the particle’s maximum speed?
The particle’s maximum speed is 17.3 m/s.
What is the maximum speed of the Mass?
The mechanical energy of the system is E = ½kA2 = 0.153 J. (b) The maximum speed of the mass is vmax = ωA = 0.78 m/s.
