Question 450782: two cities are 315 miles apart. A car leaves city A towards city B at 50mph. At the same time, a bus leaves city b at 65mph toward city A. How long with it take them to meet? Answer by rwm(914) (Show Source):
You can put this solution on YOUR website! r*t=d
r*t+r*t=d
50t+65t=315
115t=315
t=315/115=2.739 hours
If the cities were 345 apart it would take 3 hours
