Question

Working together, Paul and Dan pick 40 bushels of apples in 4.95 hours. Alone, it takes Dan 9 hours. How long would it take Paul alone?

Answer 1

Rate of Daniel - x:

4.95 (40 ÷ 9 + x) = 40

22 + 4.95x = 40

4.95x = 18

x = 40 ÷ 11

Time for Paul to gather 40 bushels:
= 40/(40 ÷ 11)

= 40(11 ÷ 40)

= 11

Hope I helped!
