A passenger train leaves the train depot four hours after the cargo train traveling in the same direction leaves the same depot
-----------------------------------------------------------
the cargo train is traveling 10 mph slower than the passenger train
-----------------------------------------------------------
given that the passenger train the freight train passes the freight train in two hours find the speed of each train
---------------------
Passenger train DATA
time = 2 hrs ; rate = r + 10 mph ; distance = 2r + 20 miles
-----------------
Cargo train DATA:
time = 6 hrs ; rate = r mph ; distance = 6r miles
--------
Equation:
distance = distance
6r = 2r+20
4r = 20
r = 5 mph (cargo train rate)
r+10 = 15 mph (passenger train rate)
