A runner travels around rectangle track with length 15 meters and width 10 meters. After travels around rectangle track two times, runner back to starting point. Determine distance
Answers
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
