Que :-

calculate the time (in hours) taken by car travelling at speed of 10m/s to travel a distance of 72km.

Ans :- 2 hour

Solution :-

Given,

$distance \: to \: travel \: by \: car = 72km$

$= 72 × 1000$

$speed = \frac{distance}{time}$

$time = \frac{distance}{speed}$

$time \: = \frac{72000}{10}$

time = 7200 sec

time = 2 hr
