Question 1048468: An aircraft carrier is travelling toward shore at the rate of 25 mph. At 3:30 pm, when the carrier is 150 miles from shore, a scout planes leaves the carrier and flies to the shore and back to the carrier. If the scout plane travels at 200 mph, at what time will the plane return to the carrier. (Assume the carrier continues on its present course and speed and the plane does not land)
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! 3:30 pm--Scout plane leaves, carrier 150 miles from shore
4:15 pm--Scout plane is at shore, carrier 131.25 miles from shore (150 miles/200 mi/hr)=45 minutes (3/4)hr;
carrier travels 18.75 miles in 3/4 hour.
The two are closing at the rate of 225 miles/hour, and they will cover 131.25 miles in 131.25/225=0.5833 hours or 35 minutes. The time 35 minutes after 4:15pm is 4:50 pm.
