Question

A runner travels around rectangle track with length = 50 meters and width = 20 meters. After

travels around rectangle track two times, runner back to starting point. Determine distance and

displacement​

Answer 1

Answer:

Displacement=0 and distance=280meters

Explanation:

He returns to starting point so Displacement is zero. I don't think you will have doubt in this.

Next comes distance and you know its is the Total path covered so find the perimeter which will be = 2(length x width)= 140 metres

He take round 2 times

so it will be 140 x 2= 280 metres.

See I answered too many questions for

please this time you give me brainliest.

Joking if you like you can give

Answer 2

Displacement will be 0 meter as displacement is the shortest distance between initial point and final point.

Distance of one round =2(50+20)

=2×70

=140m

Distance of two rounds=2×140

=280 meters
