Question

Your goal this week is to be online for a mean of only 60 minutes per day. For the first six days of the week, you are online 70, 60, 65, 40, 78, and 62 minutes. What is the most time you can be online on the seventh day and still reach your goal?

Answer 1

60*7=420
70+60+65+40+78+62=375
420-375=45
You can only be online for 45 minutes on the seventh day to reach your goal

Answer 2

Answer: The most time you can be online on the seventh day is 45 hours.

Explanation:

Hi, to answer this question we have to obtain the whole week number by multiplying the mean (60) by the seven days of the week:

Mathematically speaking:

• 60 x 7 = 420 hours

Now, we have to sum the amount of hours online of each day:

• 70+60+65+40+78+62 =375

Finally, we have to subtract that number to the whole week number:

• 420 -375 =45 hours

The most time you can be online on the seventh day is 45 hours.
