Math problem assistance…?
Hello. I received some algebra problems but there is one I am having troubles with.
There are 2 drivers D1 and D2, separated from each other for 270km. They begin driving at the same time towards each other because somewhere in the middle there is a store they want to stop. D1 travels at 75km/h and D2 at 105km/h. They got to the store the same time.
What is the distance between the store and the drivers starting point? How long were they driving?
I was of course thinking about equation systems, but my results are absurd. Could anyone advise?

270 = 105t + 75t
t = 1.5 hours
Think of it as, their combined distance with be 270km at a certain time, t.

1st prob s + (3s - 2) + (4s - 4) = 40 two s + 3s -2 + 4s -4 = 40 two combining words 8 s -6 = 40 two including 6 to the two sides 8s = 40 8 s = 6 2d prob 10/3r + 10/3 (r - 3) = ninety multiply by way of three 10 r + 10 (r -3) = 270 divide by way of 10 r + r -3 = 27 2 r = 30 r = 15
