Curtis can unload a truckload of hay in 30
minutes, but it takes Ronnie 40 minutes to do
the same. Working together, how many minutes
will it take them to unload 35 truckloads of
hay?

Answer:

600 minutes           ( 10 hours)

Step-by-step explanation:

   rate c = 1 job/30 min

   rate r = 1 job/40 mi  

     1 job / ( 1/30 + 1/40) =    1 / ( 7/120) = 17.14 minutes   per ruckload

17.14 * 35 trucks = 600 minutes
