Hi,
Working together, paul and daniel can pick forty bushels of apples in 4.95 hrs.
Had he done it alone it would have taken daniel 9 hrs.
How longwould it take paul to do it alone?
Question states*** PER hour Key
1/9 + 1/x = 1/4.95 |Multiplying thru byso as all denominators = 1
4.95x + 9*4.95 = 9x
