Solution
Mohit
Length of the rectangular field = 120 m
Breadth of the rectangular field = 75 m
∴ Distance covered in one round (perimeter)
= 2(1 + b) = 2(120 + 75) = 390 m
Hence, distance covered in 8 rounds = 390 x 8 m = 3120 m
John
Side of the field = 100 m
∴ Distance covered in one round = 4 x a = 4 x 100 = 400 m
Hence, Distance covered in 10 rounds = 400 x 10 m = 4000 m
John a covers greater distance then Mohit by = (4000 - 3120) m = 880 m
