Given :
Speed of Two Mens are 4km/h and 4m/s they stated running from same Place .
To Find :
Distance between them after 30 minutes
Solution :
as we know that, 1kmph = 18/5 m/s
then, Speed of 2nd Men is calculated by:
⇢ 4 * (18/5)
⇢ 72/5
⇢ 14.4 km/h
Distance Travelled by them after 30 minutes :
Distance covered by 1st Men
=> 4km x (½) hr
=> 2km
Distance covered by 2nd Men
=> 14.4km x (½)hr
=> 7.2km
♦ As they both started from Same Place .
Distance between them = 2 + 7.2 = 9.2km
