Fred and Sheila were on one of their Saturday adventures, this time walking along a railroad track. They came to a tunnel and decided to walk through, even though they knew they shouldn’t. After they had walked 2/5 of the way through the tunnel, they heard a train whistle blow in the distance, but couldn’t tell from which direction the train was approaching. In their fright the children began running in opposite directions. They both ran at a speed of 15 miles an hour. Each child got out of the tunnel in the nick of time. How fast was the train traveling?
