add an athlete completes one round of a circular track of diameter 200

1.	add an athlete completes one round of a circular track of diameter 200m in 40 seconds what will be the distance covered and the displacement at the end of 2 minutes 20 seconds
Answer» DISTANCE will be covered in 2M 20 s = 2x60+20= 140 sec in 40 sec he covers distance= 2πr =2π100 =200π so in 1sec=200π/40=5π now in 140 sec distance covered =140x5π =700π=700×22÷7=2200m distance=2200m displacement=0m mark me as brainlist
