Question 933278: A man is walking at an average speed of 4 miles per hour alongside a railroad track. A freight train, going in the same direction at an average speed of 30 miles per hour, requires 5 seconds to pass the man. How long is the freight train? Give your answer in feet

Man's speed = 4 mph
train speed = 30 mph
difference in speed = 30-4 = 26 mph ( same direction)
d= r * t
d= 26 * 5/3600
0.0361 miles
0.0361*5280 = length of train in feet
190.67 feet
