Question

A car is driving at 70 kilometers per hour. How far, in meters, does it travel in 3 seconds?

Answer 1

Answer is 58.3 meters

Step by step

Your equation is

70 km /1 hour = x/3 seconds

Change hour into seconds,
and change kilometers to meters

70000 /3600 = x/3

Cross multiply 70000 x 3 = 3600 (x)

210000 = 3600x

Now solve for x, divide both sides by 3600

210000 /3600 = 3600/3600 x

58.3 meters = x
