Answer: 15

Step-by-step explanation:

If a/b is equal to 5/3 then a= 5 and b= 3

3a is equal to 3 times a which is equal to 3*5

3 times 5 is 15 so 3a=15

joe and Eric have to ship 75 packages. Joe can do the job alone in 5 hours. if Eric helps, they get it done in 4 hours. How long
Umnica [9.8K]

Eric took 20 hours to do the job alone.

<u>Step-by-step explanation</u>:

<u>Given </u>:

  • Total work = 75 packages
  • Joe took 5 hours to complete the total work.

The amount of work Joe alone can do per hour = 75/5 = 15 packages.

The amount of work Joe and Eric together do per hour = 75/4 = 18.75

The amount of work Eric alone can do per hour = 18.75 - 15 = 3.75

The time Eric took to complete the entire work = 75 / 3.75 = 20 hours.
