<PRE><B>Question 650488</B>
A subway travels 60 mph from Glendale to Midtown. Another subway, traveling at 45 mph, takes 11 minutes longer for the same trip. how far apart are Glendale and Midtown.
**
let x=distance between Glendale and Midtown
travel time=distance/speed
11 min=11/60 hr
..
travel time from Glendale to Midtown at 60 mph=x/60 (faster train takes less time)
travel time from Glendale to Midtown at 45 mph=x/45
difference in travel times=x/45-x/60=11 min=11/60 hr
x/45-x/60=11/60
LCD:60*45
60x-45x=45*11
15x=495
x=33
distance between Glendale and Midtown=33 miles</PRE>
