Three buses leave Riverton and travel along the same route toward Lakeview. Bus 1 leaves first and travels at a constant speed of 50 km/h. Bus 2 leaves Riverton 6 hours after Bus 1 and travels at a constant speed of 80 km/h. Bus 3 also leaves Riverton after Bus 1 and travels at a constant speed of 100 km/h. If Bus 2 and Bus 3 catch up to Bus 1 at the same time, how many hours after Bus 1 leaves does Bus 3 leave?

Bus 2 leaves 6 hours after Bus 1, so by the time Bus 2 starts, Bus 1 has traveled 6 * 50 = 300 km. Thus, Bus 1 has a 300 km lead.
To catch Bus 1, Bus 2 needs:
time = distance/relative speed = 300/(80 - 50) = 10 hours
So Bus 2 catches Bus 1 6 + 10 = 16 hours after Bus 1 leaves.
In 16 hours, Bus 1 travels 16 * 50 = 800 km.
Since Bus 3 catches Bus 1 at the same time, Bus 3 must also travel 800 km before catching Bus 1.
At 100 km/h, Bus 3 needs 800/100 = 8 hours
Therefore, Bus 3 must have left 16 - 8 = 8 hours after Bus 1 left.

Let meeting time be t hrs
Bus 1: Distance = 50t
Bus 2: 80(t-6) = 50t
30t=480
t=16
Let bus 3 leave after x hrs
100(16-x) = 50*16
1600-100x = 800
100x = 800
x = 8
Answer: C
Bus 1: Distance = 50t
Bus 2: 80(t-6) = 50t
30t=480
t=16
Let bus 3 leave after x hrs
100(16-x) = 50*16
1600-100x = 800
100x = 800
x = 8
Answer: C
