Problem |
A rock climber is ascending a 170-foot cliff. If the climber starts at the base of the cliff and the rope is anchored 10 feet above the ground, how long does the climbing rope need to be for the entire ascent? |
|
2 |
Step |
To determine the length of the climbing rope needed for the ascent, we must consider the height of the cliff and the anchor point, plus extra length for safety and knots. |
|
3 |
Step |
The height of the cliff |
170 feet |
4 |
Step |
The height to which the rope is anchored above the ground |
10 feet |
5 |
Step |
To calculate the total length of the rope needed, you can add the height of the cliff to the height of the anchor point: |
Total rope length = Cliff height + Anchor height |
6 |
Step |
After substituting the values, we get |
Total rope length = 170 feet + 10 feet |
7 |
Step |
After adding, we get |
Total rope length = 180 feet |
8 |
Step |
So, the length of the climbing rope that is needed for the entire ascent is 180 feet. |
