Question

8. Higher Order Thinking The system of equations relates the distance, y,

from a station of two trains and the speed, x, at which they are moving.
y + 10x = 250
2.5y = -25x + 625
a. What does the system of equations tell you about the speed
of the trains?
so
b. What does the solution tell about the locations of the trains if they
left the station at the same time? If they left at different times?

Answer 1

I can’t explain it perfectly because I don’t know
But x = 20
