Rational Functions Application Question

Hey Guyzz,

Can you help me with this Application Problem; its all about ration functions.

Patricia and Chelsea can build a bike together in an hour and a half. However, if Patricia worked with Tanesha they can build the same bike 10 minutes faster. Working by herself, Patricia can build a bike 2 hours faster than Tanesha.

a) How long will it take for each of the girls to build a bike by herself.(Crying)

b) How long will it take for the three of them to build a bike together.(Crying)

Please, try your best to solve this application problem.

Thank you.(Wink)
