Question

Gerald can complete a math assignment in 2 hours and a physics assignment in 1 hour. if he has 8 hours to complete a set of assignments, how many math assignments can be complete if he decides to leave the science assignments for the next day

Answer 1

he can complete 4 math assignments

Answer 2

4

Explanation:

It is given that Gerald can complete a math assignment in 2 hours and a physics assignment in 1 hour.

Total number of hours = 8

Number of hours to complete a math assignment = 2 hours

We need to find the number of math assignments that can be complete if he decides to leave the science assignments for the next day.

Let number of math assignment be x.

Total time to complete x assignment = 2x

`2x=8`

Divide both sides by 2.

`(2x)/(2)=(8)/(2)`

`x=4`

Therefore, 4 math assignments can be complete.
