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
