After one hour the seal was:

Answer 1

Answer:

On its way up

Explanation:

Let t = 0 be time when seal is at the bottom

8 minutes later it is at the surface

3 minutes it is at bottom starting this process all over.

8+3 = 11 minutes

5 cycles = 11x5 = 55

This seal takes 8 minutes to come back to the surface to breathe

60-55 = 5 minutes.

1 hr = 60 minutes

Seal will be on its way up
