Question

A person is walking around a rectangular park of sides 150 m & 70 m respectively. He makes one complete revolution of the park in 5 mins. Calculate the total distance covered and displacement produced in 42 mins and 30 seconds.​

Answer 1

1. add 150 and 70 to get the total distance
2. divid 42 minutes from it

Answer 2

Answer:

Length of rectangular park = 30 m

Length of rectangular park = 30 mBreadth of rectangular park = 20 m

Length of rectangular park = 30 mBreadth of rectangular park = 20 m∴ Perimeter of park = 2(30 20) = 100 m

Length of rectangular park = 30 mBreadth of rectangular park = 20 m∴ Perimeter of park = 2(30 20) = 100 mSo, distance covered by the athlete in 15 rounds = 15×100=1500m
