2 cars A and B seperated by 400 Km started moving at 8a.m. towards each other with Va=100Km/h and Va=50 Km/h. At what time will the distance between them become 100 Km?
Let t be the time needed for the two cars together to travel 400-100 = 300 km.
Then, using the formula distance = rate*time, we have:

300 = 100*t + 50*t
Solve the above for t and add to 8:00a.
