Question

A zebra ran at a speed of 50 kilometers per hour. Which equation best represents the distance, y, that’s the zebra would travel in x hours?

Answer 1

The correct answer to this question would be the letter "B" y=50x

 Hope this helps you!! (:

Answer 2

You know y will always be the output, and x will always be the input. Since you only have a rate, with a starting point of 0, you just have to worry about multiplication. They’re going up at a rate of 50, so you would multiply 50 by x.
So B, y=50x.
