Answer:
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.
