Find Number of Feet

[nycmathguy]

If an object travels at five feet per second, how many feet does it travel in one hour?

Let me see.

1 hour = 3600 seconds

I think setting up a proportion works.

5 feet/x = 1 second/3600

x(1 second) = 5 feet(3600)

x = 5(3600)

x = 18,000 feet

You say?

Cool. Feels good to be right.
