Question

At a 1500 m race, Ken ran at an average speed of 200 m/min. How long did it take for Ken to finish the race? (meter = m, minute = min) min

Answer 1

`speed = (distance)/(time) \\ = > (200m)/(min) = (1500m)/(t) \\ = > (200m)/(60s) = (1500m)/(t) \\ = > (10m)/(3s) = (1500m)/(t) \\ = > t = 1500m * (3s)/(10m) \\ = > t = 150 * 3s \\ = > t = 450s \:`

This is the answer.

Hope it helps!!
