Question

Lin runs 5 laps around a track in 6 minutes.

If Lin runs 21 laps at the same rate, how long does it take her

Answer 1

Answer:

25.2

Step-by-step explanation:

6/5 is 1.2, so it takes 1.2 minutes to run one lap.

This means 21 x 1.2 = the minutes it takes to run 21 laps around the track.

Therefore it takes 25.2 minutes to run around the track 21 times.
