Question

Lin runs 5 laps around a track in 4 mins How many mins per lap is that + If Lin runs 21 laps at the same rate how long will it take

Answer 1

The answer would be 64 minutes

Answer 2

1. 48 seconds or 0.8 minutes per lap.

2. 1,008 seconds or 16.8 minutes to run 21 laps.

Explanation:

1. Turn 4 minutes into seconds which is 240 then divide it by 5 and you'll get 48 seconds per lap. 48/60 to turn it into minutes = 0.8 minutes

2. use 48 seconds and times it by 21 which gets you 1,008 seconds, then divide that by 60 which gets you 16.8 minutes to run 21 laps.
