Question

Anita can exercise for 20 minutes on her lunch break and 30 minutes after work on her 5 work days. She exercises 35 minutes on the weekend. How many hours per week does Anita exercise?

Answer 1

Determine the exercise hours for Anita during her one working days.

$20+30=50$

So Anita exercise 50 minutes per day for 5 days and 35 minutes on weekend.

Determine the number of minutes per week Anita does exercise.

$\begin{gathered} H=50\times5+35 \\ =250+35 \\ =285 \end{gathered}$

Determine the number of hours in 285 minutes.

$285\cdot\frac{1}{60}=4.75$

Thus number of hours Anita exercise in a week is 4.75 or 4 hours 45 minutes.
