Question 62030
First Train:
Rate: 70km/h
Time: t + 2
Second Train:
Rate: 90km/h
Time: t
The sum of the two train's distances is equal to the total distance between the two.
Distance = Rate * Time
First Train:
70(t + 2)
70t + 140
Second Train:
90(t)
90t
70t + 140 + 90t = 1420
160t = 1280
t = 8
First Train:
Rate: 70km/h
Time: t + 2 = 8 + 2 = 10
Second Train:
Rate: 90km/h
Time: t = 8
