Question

Max spends three times as long on his math homework than he does on his science homework. if he spent a total of 64 minutes on math and science homework last night, how long did he spend on math homework

Answer 1

Let m=math and s=science

m=3s

m+s=64

So using substitution,

3s+s=64

4s=64

s=16

So m=64-16=48 minutes
