An athlete completes one round of a circular track of diameter 200 m in 40 s what will be the distance covered and displacement at the end of 2 min 20s

Sagot :

Answer:

700π m ~ 2199 m

Step-by-step explanation:

diameter = d = 200 m

2 min 20s = 140 s

1 round / 40 s

140 = 40 * 3 + 20

so the athlete will cover 3 round and half

1 round = d * π

covered = c = 3 * 200 * π + 200/2 * π = 700 * π
