Question 541103: A helicopter traveling at an average rate of speed of 150 miles per hour left from a downtown terminal at noon after a train, which had departed from the same terminal at 9 a.m. If the helicopter overtook the train at 2:00 p.m., find the average speed of the train. Answer by oberobic(2304) (Show Source):
You can put this solution on YOUR website! The helicopter flew for 2 hours at 150 mph, so it traveled 300 miles.
.
The train also traveled 300 miles, but it traveled for 5 hrs (9 a.m. to 2 p.m.).
.
300 miles/5 hr = 60 mph
.
The average speed of the train is 60 mph.
