Explanation:

I did this assignment :D

Answer 2

480 mph and 600 mph

Explanation:

we can call the first planes speed x, and the other x+120 because it is going 120 mph faster. Because distance = rate * time, that means that 1620 = 1.5*(x+x+120) and then you just solve the equation

1620=1.5*(x+x+120)

1620=1.5*(2x+120)

1620=3x+180

1440=3x

x=480

x+120=600
