<PRE><B>Question 655720</B>
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)
