Question 244230: A plane left at 3pm flying west at 450 miles per hour. At 3:30 pm another plane left the same airport flying west at 500 miles per hour. At what time did the second plane overtake the first plane? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! first plane speed 450 mph
second plane speed 500 mph
rt=d
RT=D
30 minutes head start=1/2 hour
450*(t+1/2)=500(t)divide by 50
9*(t+1/2)=10t
9t+4.5=10t
simplify
4.5 hours =t
They pass at 7:30 pm
