Answer:

88 Math problems

Step-by-step explanation:

Count first how many 30 minutes are there in 2 hours.

2 hours = 120 minutes

120 minutes ÷ 30 minutes = 4

*So there are four 30 minutes in 2 hours

Since he can do 22 math problems in 30 minutes, multiply 22 by 4.

22 x 4 = 88

To check, add the following:

30 minutes - 22 math problems

30 minutes - 22 math problems

30 minutes - 22 math problems

30 minutes - 22 math problems
