Question

A car is driving at 65 kilometers per hour. How far, in meters, does it travel in 3 seconds?

meters
Give your answer to the nearest meter.

Answer 1

Explanation:

65 km / h = 65,000 m / 3600 s

what do we need to multiply 3600 with to get 3 ?

3600 × f = 3

f = 3/3600 = 1/1200

now, we need to multiply 65,000 by the same factor to get how many meters the car is driving in these 3 seconds :

65000 × 1/1200 = 65000/1200 = 54.16666666...

so, rounded, it travels 54 meters in 3 seconds.
