Question

Mrs Davis worked 42 hr 35 min last week how many hours and minutes did she average in each of the five days

Answer 1

8 hours and 31 minutes

Explanation:

To get an average, you take the total time and divide it by the total days. Here, it would be 42 hours and 35 minutes divided by 5 days. You can convert the hours to minutes, and get 42x60=2520 plus the 35 minutes to get 2555 minutes. Divise that by 5 and you get 511 minutes per day. Since they're asking for hours and minutes, divide 511 by 60 to get 511÷60=8 with remainder 31.

Answer 2

8 hours and 31 minutes per day

Explanation:

`\implies 42 \text{hours} * 60\text{minutes}=2,250 \text{minutes}`

`\implies2,520 +35 = 2,555`

`\implies 2,555 /5 = 511`

`\implies 511/60 = 8 (31)/(60) = 8\text{hours}, 31 \text{minutes per day}`
