A train traveling between 2 towns arrives 9 minutes late when traveling at 36
mph. When it travels at 27 mph the train arrives 39 minutes late. How many
miles are there between the two towns?
----------------
Fast Rate DATA:
rate = 36 mph ; distance = x miles ; time = d/r = x/36 hrs
---
Slow Rate DATA:
rate = 27 mph ; distance = x miles ; time = d/r = x/27 hrs
--------------------------
Equation:
slow time - fast time = (1/2) hr
(x/27) - (x/36) = 1/2
(36x - 27x)/[27*36) = 1/2
9x = (27*36)/2
x = (27*2)
x = 54 miles
Distance between the towns is 54 miles.
