A plane leaves the airport and flies East at 200 mph. 2 hours later,
another plane leaves and flies West at 150 mph. Write and solve a
system of linear equations that can be used to determine when the
planes are 750 miles apart.
**
let x-2=travel time of plane flying East
x=travel time of plane flying West(when planes are 750 miles apart)
distance=*travel time*speed
equation:
150(x-2)+200x=750
150x-300+200x=750
350x=1050
x=3
planes are 750 miles apart after 3 hrs
