Question 895981: two planes leave an airport at the same time one flying east the other flying west the east bound plane travels 110 mph slower they are 1540 mi apart after 2 hr find the speed of each plane Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Think of one plane as standing still and the
other plane flying at the sum of their speeds
Let = the speed of the faster plane
-------------------------------
------------------
The west bound plane flies at 440 mi/hr
The east bound plane flies at 330 mi/hr
check:
East bound train: mi
-------------------
West bound train: mi
------------------- mi
OK
