Question

Working together, Jasmien and Sumalee can pick forty bushels of apples in 5.48 hours. Had she done it alone it would have taken Sumalee 9 hours. Find how long it would take Jasmine to do it alone.

Answer 1

Basically you need to use the same formula we used last time. Last time we were to find the number of hours that 2 guys would need to complete 1 job working together; here you already know that the 2 girls can complete the job working together in 5.48 hours. The only think you need to find is how long it would take Jasmine to do the job alone.

Answer 6

Neither Jasmine nor Sumalee is a mathematical quantity; these are labels.

Model your solution of this problem on the previous one on which we collaborated.

40 bushels
-------------------------- = 5.48 hours. Solve for S.
40 bushels 40 bushels
----------- + -------------
9 hours S hours

Answer 7

Hm, I'm confused on this part @mathmale

Answer 8

try this J + S = 40bushels / 5.48hours
S = 40bushels / 9hrs
J = 40bushels / ?hrs

Answer 9

40B/5.48hr = 7.3rounded -> bushels per hour
S -> 40B/9hr = 4.44 -> bushels per hour
J -> (J+S) -S = 7.3 -4.44 ->bushels per hour
