a train makes a trip at 65 mph. A plane traveling 130 mph makes the same trip in 3 fewer hours. Write and solve an equation to find the distance of the trip.
-----
Let the distance be "x" miles.
------
Equation:
train time - plane time = 3 hrs
x/65 - x/130 = 3
----
Multiply thru by 130 to get:
2x - x = 390
x = 390 miles
