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.
