Preeti is going on her moped at a speed of 24km/hr. How much time will she take to cover 720 metres?

Given:

Preeti is going on her moped at a speed of 24km/hr.

To do:

We have to find the time taken to cover 720 metres. Solution:

We know that,

$1\ km/hr=\frac{5}{18}\ m/s$ 

Therefore,

Speed of the moped$=24\times\frac{5}{18}\ m/s=\frac{20}{3}\ m/s$

Time taken to cover 720 metres$=\frac{Distance}{Speed}$

$=\frac{720}{\frac{20}{3}}\ s$

$=36\times3\ s$

$=108\ s$

She took 108 seconds to cover 720 metres.
