Allie was done with gymnastics practice at 7: 30. at practice,she tumbled for 20 minutes. then she worked on the balance beam for 10 minutes. allie also practiced on the trampoline for 15minutes. what time did she start practice?

6:45

Step-by-step explanation:

I would recommend working backwards in this problem.

Allie worked out for a total of 20+10+15 minutes = 45 minutes

If she finished at 7:30, that means she started 45 minutes earlier, which would be at 6:45.
