Two airplanes leave the airport at the same time, flying in opposite directions. one plane flies 150 miles per hour faster than the other. after 4 hours, they are 2,200 miles apart. what rate are they each flying? 150 mph and 300 mph 200 mph and 350 mph 250 mph and 400 mph 225 mph and 375 mph

option B

200 mph and 350 mph

Step-by-step explanation:

Suppose speed of one plane = x miles/h

               speed of other plane = (150 + x) miles/h

distance between two plane after 4 hours = 2200 miles

To solve this question we will add up both plane's distance covered in 4 hours and equal them to 2200 miles

Formula to use

distance1 = speed x time

                = x(4)

distance2 = speed x time

                = (150+x)(4)

Total distance covered

2200 = distance1 + distance2

2200 = 4x + (150+x)4

2200 = 4x + 600 + 4x

2200 = 8x + 600

8x = 1600

x = 1600/8

x = 200 miles/h

x + 150 = 200 + 150 = 350miles/hour

because they could drop even lower..
