Answer:

Given:

A runner travels around rectangle track.

length of track= 50 meters

width of track = 20 meters

runner travels around the rectangle track two times  and finally finishes back at the starting point.

To Find:

Distance and displacement of runner.

Solution:

Distance traveled by runner = 2 (perimeter of rectangle)

Perimeter of rectangle = 2(L+B)

L = 50 m     B = 20 m

perimeter of rectangle = 2(50+20)

                                       = 140 m

Distance traveled by runner = 2 (perimeter of rectangle)

                                                = 280 m

Displacement :

It is the shortest distance between initial and final position or the shortest path of travel

initial position of runner = final position of runner

displacement = 0 m

Distance traveled by runner = 280 m

Displacement traveled by runner = 0 m
