Question

Alex usually runs for 21 hours a week, training for a marathon. If he is unable to run for 3 days, describe how to find out how many hours of training time he loses, and write the appropriate integer to describe how it affects his time.

Answer 1

If he runs for 21 hours per week, how many hours does he run per day? There are 7 days in a week, so this would be 21/7. Then if he doesn't run for three days, you need to multiply this by 3.
