Question 348056: please help me with this question jodie bicycles 7km faster than dennis in the same time it takes dennis to bicycle 60km, jodie can bicycle 81km. How fast does each bicyclist trave? Thank you for your help! Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! dennis's speed be x kph
Jodie's speed = x+7 kph
...
Dennis 60 km
Jodie = 81 km
...
The times are same
...
60(x+7)=81x
60x+420=81x
81x-60x=420
21x=420
/21
x=420/21
x=20 kph speed of Dennis
x+7 = 20+7 = 27 = Jodie's speed
