Question 1035384: a plane left the airport at 3pm flying west at the rate of 450 miles per hour. at 3:30 pm, another plane left the same airport, flying west at the rate of 500 miles per hour. at what time did the second plane overtake the first plane? Answer by FrankM(1040) (Show Source):
You can put this solution on YOUR website! One step at a time -
Plane 1 went 450 miles/hr for 30 minutes, and traveled 225 miles.
When plane 2 took off, it was going faster than plane 1 by 50 miles/hour, so, to catch up by 225 took 225/50 or 4.5 hours.
