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, we can use a proportion.
Inessa ran 3 laps in 10 minutes.
So, the rate at which she runs laps is 3 laps/10 minutes = 3/10 laps per minute.
Using the same rate, we can set up a proportion:
3/10 = 5/x
Cross-multiplying, we get:
3x = 50
Dividing both sides by 3, we get:
x = 50/3 = 16 2/3 minutes
Therefore, it would take Inessa 16 2/3 minutes to run 5 laps at the same pace.
