Question

Starting from a height of 1129 ft you gain 99 Dr each additional hour of climbing ​

Answer 1

1129 + 99x

Explanation:

Let us use x in this equation; x = amount of hours.

You are currently at 1,129 ft.; so lets start with that.

After then you don't know how many hours you climb but you know at what pace. So you use a variable to plug in with numbers later.

So your equation turns into;

1,129 + 99x
