Question

Lin runs 5 laps around a track in 6 minutes.

1. How many minutes per lap is that?
2. How many laps per minute is that?
3. If Lin runs 21 laps at the same rate, how long does it take her?

Answer 1

1. 6 minutes / 5 laps = 6/5 minutes per lap = 1.2 minutes per lap
2. 5 laps / 6 minutes = 5/6 laps per minute = 0.84 laps per minute
3. 21 * 5/6 = 105/6 = 17.5 minutes
