Inessa ran 3 laps in 10 minutes. How long would it take her to run 5 laps at this pace?

1 1/2 minutes
15 minutes
16 2/3 minutes
20 minutes

To find out how long it would take Inessa to run 5 laps at the same pace, you can set up a proportion:

laps / minutes = laps / minutes

3 / 10 = 5 / x

Cross multiplying, you get:

3x = 50

Dividing both sides by 3, you get:

x = 16 2/3 minutes

Therefore, it would take Inessa 16 2/3 minutes to run 5 laps at this pace.
