Question

Jodie bicycles 8 km/c faster than Javier. In the same time it takes Javier to bicycle 57 km, Jodie can bicycle 81 cm. How fast does each bicylist travel?

Answer 1

suppose the speed of jevier's cycle is x.
hence speed of jodie's cycle = x+8.

=> 57/x=81/(x+8)
=> 81x=57x + 8*57
=> 81x-57x=8*57
=> 24x=8*57
=> x=19
x+8= 19+8=27.
