Question

Yael worked out at a gym for 3 hours. Her workout consisted of stretching for 21

Answer 1

21 + 39 = 60 minutes ( 1 hour)

So for the remaining time she lifted weights for about 2 hours.

3 hours = 180 minutes

180 - 60 = 120

About 66% of the remaining time Yael used to lift weights.

To be accurate 66.6% ( the last 6 repeating a infinite amount of time aka it doesnt end)
