Use this correlation distance-time-speed to find the answer
d = vt
d stands for distance, v stands for speed/velocity, t stands for time

The sum of the distance must be 250 miles, so they could be 250 miles apart.
The time must be the same for the two cars.
distance 1 + distance 2 = 250
v₁t + v₂t = 250
70t + 55t = 250
125t = 250
t = 250/125
t = 2

They will be 250 miles apart in 2 hours
