So here’s an easy-ish brain teaser. There will not be any prizes.

A train is 100 meters long. It goes 100 meters per minute. The tunnel is 100 meters long. How much time would it take the train to go through the tunnel?

    0s. If the train is the same length as the tunnel, it wont go anywhere, no matter how fast it’s going!

    Not exactly, Dragonfly.
    The tunnel is not moving.
