How do you calculate the speed of a car on the road?

if you are in a plan going 140 miles an hour how do you make observation from an airplane to determine the speed of a car on the road. needing speed = distance /time. Distance = speed x time. Time = distance/speed.

What is the average speed of 2450 miles per hour?

The answer is 2450 / 5 = 490 mph (miles per hour) average speed. If you want the result in km/h, you can convert from miles to km to get 788.58 km/h. Distance formula

What is the average speed for the entire trip?

In 6 hours the car travels 480 km. Its average speed for the trip is 80 km/h. The time taken per km is 60/80 minutes = 3/4 minutes = 45 seconds. The Answer: The Average Speed for the Entire Trip is 80 km/h. The car travels 240 km at 60 km /hr. That takes 4 hours. Then the car travels 240 km at 120 km/hr. That takes 2 hours.

What is the value of V if the speed is 48 km/h?

A car moves a distance of 200 m. It covers the first half of the distance at speed 40 km/h and the second half of the distance at speed v. If  the average speed is 48 km/h, then the value of v is- Medium View solution View more More From Chapter

What is the relationship between speed and distance?

Distance is equal to speed × time. Time is equal Distance/Speed. Distance = Speed × Time Speed = Distance / Time Time = Distance / Speed.

What is the formula to calculate distance from time?

Time Speed Distance Formula. Distance is equal to speed × time. Time is equal Distance/Speed. Distance = Speed × Time Speed = Distance / Time Time = Distance / Speed.

How to calculate time and speed in a calculator?
