A one-half mile long train is moving at 45 mph when it passes a car traveling in the opposite direction at 60 mph.
To the nearest second, how many seconds until the last car of the train is past the car?
:
The relative speed of the train and the car: 45+60 = 105 mph
How long to travel 1/2 mile at this speed
.5%2F105 * 3600 = 17.143 seconds
