Question

two trains leave at the same time traveling in opposite directions. If one train is going 3 times as fast as the other train and the trains are 240 miles apart after 1.5 hours, then how fast is each train moving. Help please

Answer 1

You have to set up a distance rate and time equation

Answer 2

d=rt

Answer 3

One second I'll set it up

Answer 4

so would this work 3x-240<1.5

Answer 5

no you would have to do 1.5x+1.5(3x)=240

Answer 6

which would become 6x=240
x=40

Answer 7

then you plug it into each train so train 1 is moving 40 mph while train 2 is moving 120 mph
