Josie does 9 minutes of stretches before she runs. She runs for
20 minutes. Then she does 7 minutes of cool
down exercises. The clock shows the end time 3:45 of
her workout. At what time does Josie start her
workout? Describe how you found the time.

Josie starts working out at 3:09

Step-by-step explanation: I found this answer by adding the workout time together.

3:09

Step-by-step explanation:

First add the total time of the workout

20+9+7=36

then subtract the end time 3:45 with the workout time:

3:45-00:36=3:09

Check work:

3:09+00:36=3:45
