Question

Quincy was stuck inside during an afternoon rainstorm. He spent 20 minutes reading, 18 minutes eating lunch, 12 minutes playing cards, and 10 minutes drawing.
For every 10 minutes Quincy was inside he spent 3 minutes doing what?

Answer 1

This problem is dealing with ratios of time spent on each activity.

To calculate the ratio of time spent on each activity, we first gather up all the minutes:

20 + 18 + 12 + 10 = 60 minutes

We then divide each activity's time by 60 minutes to get each ratio:

Reading - 20 : 60 -> 1 : 3
Lunch - 18 : 60  -> 3 : 10
Playing cards - 12 : 60 -> 1 : 5
Drawing - 10 : 60  - > 1 : 6

The last part reads, "For every 10 minutes Quincy was inside he spent 3 minutes doing what?" 

This means that the problem wants to you to find which activity for which Quincy spent 3 minutes every 10 minutes inside. In other words, which activity has a 3 : 10 ratio?

It was lunch!

Answer 2

20 + 18 + 12 = 40

40 /10 = 4

(4)(3) = 12

On what activity did he spend 12 minutes?
