Two planes are 1620 miles apart and are traveling toward each other. one plane is traveling 120 mph
faster than the other plane. the planes meet in 1.5 hours. find the speed of each plane.

480 mph and 600 mph

Step-by-step 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

answer: give more info

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
