Two planes leave an airport at the same? time, one flying? east, the other flying west. the eastbound plane travels 90 mph slower. they are 3480 mi apart after 4hr. find the speed of each plane.

2x + 2(x-90) = 3480

2x + 2x - 180 = 3480

4x = 3660

x = 915 mph Plane 1 westbound

915-90 = 825 mph plane 2 eastbound

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
