Question

In a certain skyscraper, the elevators whisk you to a restaurant in the skyscraper at a speed of 800 feet

in 10 seconds. If the restaurant is 300 feet up, how long will it take you to reach the restaurant by
elevator?

Answer 1

`3(3)/(4)` seconds

Explanation:

So you travel 800 feet in 10 seconds. If you divide that by 2, then you travel 400 feet in 5 seconds, or 100 feet in 5/4 seconds. Multiply by 3 to get 300 feet in 15/4 seconds, or 15 feet in
`3(3)/(4)` seconds.
