Question 527875
amglea made a trip by bus in 16hours and the return trip by car in 20 hours. the bus traveled 10 times faster than the car. How far was the trip?
---------------
b = bus speed
c = car speed
-----
b = 11c
d = 16*11c = 20c
c = 0
----------
There's no solution.  If the bus is 11 times as fast, it would take 1/11 of the time, not 16/20.
