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.
b) How long will it take for the three of them to build a bike together.
Please, try your best to solve this application problem.
