Annabelle is taking the Polar Express ALL the way to the North Pole! The Polar Express is 100 meters long and it takes 30 second
vlada-n [284]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To solve this, we will be doing a semi-alternate route, but it will get us to our answer...


400 / 100 = 4

30 / 4 = 7.5 seconds

60 * 60 * 7.5 = 27,000 meters per hour

<em></em><em>Lets plug it into our meters to miles formula...</em>

27,000 / 1,609.344 ~ 16.777 miles per hour


So...

The answer is:  The Polar Express was going 27,000 meters per hour (or roughly close to 16.777 miles per hour)...
