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

Mridul will need 14 minutes and 24 seconds to jog six rounds.

The total distance that Mridul jogs in one round is 2 * (100 + 80) = 360 meters. To convert this distance from meters to kilometers, we divide by 1000, which gives us a total distance of 0.36 km per round.

Mridul jogs at a rate of 9 km per hour, so in one hour he can cover 9 km. To find how long it takes him to cover 0.36 km, we divide the distance he covers in one hour by the total distance per round:

9 km / 0.36 km per round = 25 rounds per hour

So, it takes Mridul 1 hour / 25 rounds per hour = 0.04 hours, or 2.4 minutes, to jog one round.

To jog 6 rounds, Mridul will take 6 rounds * 2.4 minutes per round = 14.4 minutes.
