Question

The Polar Express is 100 meters long and it takes 30 seconds to cross Santa’s 400m ice bridge. What speed is the train going at?

Answer 1

Here is your answer

____________________________________________________________

Total Distance required for the last compartment to travel =

Lenght of the train + Lenght of the Bridge = 100 + 400 = 500

Speed = Distance / Time

Speed = 500 / 30 = 16.66 m/s
