Brooke will take 15 x 2 = <<15*2=30>>30 minutes to answer all math problems.

It will take him 6 x 30 seconds = <<6*30=180>>180 seconds to answer all social studies problems.

In minutes, this is equal to 180/60 = <<180/60=3>>3 minutes.

It will take him 10 x 1.5 minutes = <<10*1.5=15>>15 minutes to answer all science problems.

Therefore, Brooke will take 30 + 3 + 15 = <<30+3+15=48>>48 minutes to finish his homework.

For homework, Brooke has 15 math problems, 6 social studies problems, and 10 science problems. He can answer each math problem for 2 minutes while answering each social studies problem takes him 30 seconds. If he can answer each science problem in 1.5 minutes, how long will it take Brooke to answer all his homework?
