Mona likes to ski. a full lap includes a 4 minute ride up the ski lift and then it takes her 5 minutes to do one run. how long will it take her to do 5 full laps?

She will take 45 minutes to finish 5 laps.

Explanation:

 A full lap includes a 4 minute ride up the ski lift and then it takes her 5 minutes to do one run

So time for one full lap = 4 minutes + 5 minutes = 9 minutes.

We need to find how long she will take to finish 5 laps.

Number of laps = 5

Total time taken = Number of laps x Time for one lap.

                             = 5 x 9

                             = 45 minutes.

So, she will take 45 minutes to finish 5 laps.
