Question

each evening, Marisol spend at least twice as much time reading as she spends doing homework. If Marisol works on her homework for 42 minutes, how much time can she spend reading?

Answer 1

multiply 42 times 2 and your answer will be 84

Answer 2

To get the result we can use knowledge that reading is 2 times longer than HW.
To find this value we just have to multiply 42 times 2 so
40*2=80
Its 1 hour and 20 min - its the result
