Workout question in total minutes

Question

On a cycle machine, if I do a 5 minute warmup, followed by a 1 minute cruise, followed by another 15 seconds, and do this 10 times finished with a 5 minute cool down, how many total minutes is this?

Answer 1

5 + 5 = 10 mins warmup/cool down

 

15 seconds = 1/4 minute = 0.25 minutes

 

1.25(10) = 12.5 minutes

 

12.5 + 10 = 22.5 total minutes
