Question

Prreti is going on her moped at a speed of 24km/hr. How much time will she take to 720m.

Answer 1

In order to convert from the speed in kmph or km/hour into speed in meters/sec, we multiply by 5/18 or 1000/3600.

So speed in m/sec = 24 * 5/18 = 20/3 m/s

Time duration for covering 720 m = distance/speed 
   =  720/(20/3) sec
   = 108 sec.
   = 1 minute 48 seconds.
