bill can mow the lawn in two hours, and his younger brother tom can mow it in three hours. if both brothers mow the lawn together, how many hours will it take them?
Answer provided by our tutors
let 'x' represent the amount of time it takes them to mow together, then:
1/x = 1/2 + 1/3
solving for 'x' we have x=1.2
.2* 60 = 12
it will take them 1 hour and 12 minutes to mow the lawn together (1.2 hours)
