Question

A 400 meters running track has two straight sections, each of length 120 meters and two semicircular ends. calculate the total length of the of the curved sections of the track.​

Answer 1

160 m

Explanation:

Length of running track = Total Length of straight sections + Total length of curved sections

Solving :

⇒ 400 m = 2 x 120 m + Total Length of curved sections

⇒ Total Length of curved sections = 400 m - 240 m

⇒ Total Length of curved sections = 160 m

Answer 2

Answer: 160
Solution: 400-120x2=160
