Question 619264: Elena bicycles 8km/h faster than Dennis. In the same time it takes Dennis to bicycle 42km/hr, Elena can bicycle 66km/hr. How many km/hr does Dennis bicycle. How many km/hr does Elena bicycle. Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! The problem is misstated. 42 km/hr should be 66 km and
66 km/hr should be 66 km.
With that understood,
Let = the time it takes Dennis to bicycle 42km = Dennis's speed = Elena's speed, and = Elena's speed also
----------------------
Elena's speed is 22 km/hr
------
check:
Dennis's speed = = 14 km/hr
OK
