If sally walked 1⁄2 kilometer in 1⁄4 hour, how fast, in kilometers per hour, was she walking?

So you need an hour in order to get your answer, but we already know that every 1/4 of an hour is equal to 1/2 of a kilometer, meaning that if we multiply 1/2 of a kilometer 4 times, we get 2 kilometers, in which Sally ran for an hour. The answer is 2 kilometers per hour.

Hope this helped!
