Question

A boy is cycling around a rectangular park of sides 100×70 calculate the distance covered and displacement when he completes 3 round

Answer 1

Answer:

distance = 1020   displacement = 0

Explanation:

length= 100

width= 70

distance covered in 1 round= perimeter of park

                                               = 2 (l+b)

                                               = 2(100+70)

                                               = 2 x 170

                                               = 340

distance covered in 3 rounds= 3 x 340

                                                  = 1020

displacement = 0

As, the boy is back to his original starting point
