Question

A man jogs around a rectangle Park 100m by 80m at the rate of 6km per hour how much time he take in jogs 6 rounds Solutions

Answer 1

Answer:

Answer:14 min 25 sec

perimeter of park=2(l+b)=2(100+80)=2*180=360 m

distance of 1 round =360 metres

distance of 6 rounds=360*6=2160 metres

speed of mridul=9 kmph=9*1000/3600=2.5 m/s

Speed =distance/time

→time=dist./speed=2160/2.5=865 sec=14 min 25 sec
