Answer:
1129 + 99x
Step-by-step 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
