Question

Alan has reached 25% of his weekly exercise time goal so far this week. If he has exercised for a total of 42 minutes this week, what is his weekly exercise time goal in minutes ​

Answer 1

His weekly exercise time goal is 168 minutes.

Explanation:

This question can be solved using a rule of three.

42 minutes is 25% = 0.25 of the total

x minutes is 100% = 1 of the total.

Then

42 minutes - 0.25

x minutes - 1

`0.25x = 42`

`x = (42)/(0.25)`

`x =  168`

His weekly exercise time goal is 168 minutes.
