Question

If Tina cuts a lawn by herself, she can finish in 5 hours. If bill cuts the same lawn by himself it takes him two hours longer than Tina. How long will it take them both working together?

Answer 1

Tina can finish in 5 hours
Bill takes two hours longer than Tina.
5+2=7
Bill takes 7 hours to cut the lawn.
7+5=12
It takes both of them working together 12 hours. Hope this helped!
