Lin runs 5 laps around a track in 15 minutes.

Question

1- How many minutes per lap is that?

2- How many laps per minute is that?

3- If Lin runs 24 laps, how long does it take her?

Answer 1

1. 3 minutes per lap: 15/5 = 3
2. 1/3 lap per minute: 5/15 = 1/3
3. 72 minutes = 1 hour & 12 minutes = 72/60 hours = 6/5 hour = 1.2 hours; 24x3 = 72
