Question

Jimmy has studied 22 hours over the last 10 days for the ACT. He studied either 2 hours a day or 3 hours a day. During the 10 day period, how many days did Jimmy study for three hours a day?

Answer 1

8x2

2x3

The total number of hours studied in 10 days is 22 hours. Now the question says jimmy has either studied 2 hours a day or 3 hours a day. To find this the calculation is as follows:

For eight days jimmy has studied for 2 hours, so the total time that he has studied makes up to be 16 hours. Now for the other two days jimmy has studied for 3 hours which adds up to be 6 hours. So the total time studied is 6 hours.

Total= 16+6=22 hours
