Question

a car travels at the speed of 72 km/hour. how much distance will it travel in 27 seconds?

Answer 1

Convert it into m/s
by multiplying it with 5/18
72×5/18
=20m/s
so in 27 sec
27×20=540m

Answer 2

speed - distance/time
> distance - speed × time

so, Distance = [72/60×60] × 27

> Distance = 0.02 × 27 = 0.54 km
