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?
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!
