Another Advanced Algebra Question!

[From: ] [author: ] [Date: 12-11-12] [Hit: ]
.Qis quantity = 1;1 = [ c1 + c2 ] 2....1 = c1 t and 1 = c2 [ t+3].......
two cranes can unload a ship together in 2 hours. the faster crane takes 3 hours less than the slower crane, if each were to unload the same ship alone, how long does it take for each crane to unload?

-
Q = rate x time...Q is quantity = 1; 1 = [ c1 + c2 ] 2....1 = c1 t and 1 = c2 [ t+3]...

c1 = 1 / t & c2 = 1 / [ t + 3 ].......c1 + c2 = 1 / 2 = 1/t + 1 / [t + 3 ]---> t = 3

thus c1 = 1 / 3 and c2 = 1/ 6...times 3 & 6 hrs
