Question 655720: two small planes start from the same point and fly in opposite directions the first plane flying 55 mph slower than the second plane. In 2 hours planes are 510 miles apart. Find rate of slower plane Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! two small planes start from the same point and fly in opposite directions the first plane flying 55 mph slower than the second plane. In 2 hours planes are 510 miles apart. Find rate of slower plane
--------------------
faster plane DATA:
rate = x mph ; time = 2 hrs ; distance = 2x miles
-----
slower plane DATA:
rate = x-55 mph ; time = 2 hrs ; distance = 2x-110 miles
-----
Equation:
distance + distance = 510 miles
2x + 2x - 110 = 510
4x = 620
x = 155 mph (faster plane rate)
----
x - 55 = 100 mph (slower plane rate)
