Let x = the shorter piece and Let y = the longer piece.
(3/4)x = 120
x = 120 / (3/4)
x = 120 * (4/3 = 480/3) = 160 feet
y = 160 + 12
7.2 because you just add the -4.8 to cancel out the -4.8 on the right side. and you get 7.2
Train A speed= 70 km/h north
Train B speed= 75 km/h south
Opposite directions= add speeds 70+75=145
Distance= 435 Km
Time= d/s; 435/145= 3 hours
It would take 3 hours for the trains to be 435 kilometers apart
