Question

Mai runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take Mai to complete 4 laps of the track?

Answer 1

The total distance Mai runs is 400(4), so the distance equals 1,600 meters. If it takes her 250 meters per minutes, then if you divide 250 with 1600– it’ll take her 6.4 minutes

Answer 2

It take 6 minutes 24 seconds to complete 4 laps

Explanation:

Speed=distance /time

To get time

Time=distance/ speed

In this case, distance is 4 laps of 400 meters, so we have to multiple 4 x 400=1600 meters

Speed= 250 per minute

Time=distance/ speed

Time=1600 meters /250 meter per minute =6,40 minutes is the same 6 minutes 24 seconds
