You can put this solution on YOUR website! if a plane leaves at noon traveling at 180 mph and another plane leaves at 1 pm traveling at 330 mph, how long until they are even?
------------------
Noon plane DATA:
rate = 180 mph ; time = x hrs ; distance = 180x miles
-----
1 pm plane DATA:
rate = 330 mph ; time = x-1 hr ; distance = 330(x-1) miles
------------------
Equation:
distance = distance
180x = 330x-330
-150x = -330
x = 2.2 hrs = 2 hrs 12 minutes (time it will take for the 1pm to catch the noon)
