Question

Michelle can swim 4 laps in 6 minutes and 12 seconds. If michelle swims at the same pace, how long would it take her to swim 10 laps?

Answer 1

6x60=360+12=372/4= 93x10= 930/60=15.5

It would take Michelle 15 minutes and 50 seconds to swim 10 laps

Answer 2

9 laps takes 5 minutes 25 seconds.

Explanation:

Here is given:

4 laps takes 6 minutes 12 seconds.

We have to find how long 1 lap takes.

4/4 6/4 12/4 --> 1 lap takes 2 minutes 33 seconds.

Now, multiply each by 9 because you want to find 9 laps, so:

1x9 2x9 33x9 --> 9 laps takes 5 minutes 25 seconds.

Hope this helps :)
