x = 55
do you mind helping me with this question please. A train leaves Philadelphia at 1:00 PM. A second train leaves the same city in the same direction at 6:00 PM. The second train travels 150mph faster than the first. If the second train overtakes the first at 8:00 PM, what is the speed of each of the two trains?
yes

let the no. be x
if 65 is added then no. will be x+65.
According to the question, we get:
the result is 45 less than 3 times the no.
the result=3x-45
x+65=3x-45
x-3x=-65-45
-2x=-110
x=-110/-2
x=55.
