How Fast is Annabelle's Train Going to the North Pole?

What speed is the train going at?

(30, 45, 60, 80 km/h)

Answer:

The train is going at a speed of 60 km/h.

Annabelle is taking the Polar Express all the way to the North Pole. The Polar Express is 100 meters long and it takes 30 seconds to cross Santa’s 400m ice bridge. When the train reaches the bridge, the nose of the locomotive has to travel 400 m to get from one end of the bridge to the other end. Then the whole train is on the bridge, so the nose of the locomotive has to go another 100m to drag the whole train off the bridge, making a total of 500 meters for the whole train to cross the bridge.

By calculating the speed using the given data, we get:

500 m / 30 s = 16-2/3 m/s = 60 km/hr

Therefore, the train is going at a speed of 60 km/h to reach the North Pole.
