Answer 1

Julius needs 2124 calories to exercise 30 minutes per day, 6 days a week.

Step-by-step explanation:

Given that He burns calories at a rate of 708 calories per hour.

`r=708\text{ cal/hr}`

The number of calories he need to excercise 30 minutes per day, 6 days a week is;

`\text{time t = 30 min/day }*\text{ 6 days/wk}=180\text{ minutes/wk = 3 hours/wk }`

The amount of calories can be calculated as;

`\begin{gathered} A=\text{rate}* time \\ A=708\text{ cal/hr }*3\text{ hours/wk} \\ A=2124\text{ calories/wk} \end{gathered}`

Therefore, Julius needs 2124 calories to exercise 30 minutes per day, 6 days a week.
