Train Trouble

This Technology Problem of the Week (tPoW) challenges students to use proportional reasoning to determine the speed of a train that two children in a tunnel evade by running in opposite directions, given only the kids' relative starting position and speed as they run out of the tunnel. It links to the Geometer's Sketchpad sketch "Train Tunnel." Solve and explain your solution; download hints and answer checks. Free registration is required.
