A car travels 225 miles in the same time that a train travels 360 miles. if the speed of the train is 30 miles per hour faster than the speed of the car, what is the speed of the car?
-------------
Car DATA:
distance = 225 miles ; rate = x mph ; time = d/r = 225/x hrs.
-----------------------
Train DATA:
distance = 360 miles ; rate = x+30 mph ; time = d/r = 360/(x+3) hrs
-------------------------
Equation:
time = time
225/x = 360/(x+3)
---
Solve for "x":
