The anchor's new position is 7.2meters below the surface of the ocean.
Tracking the movement of the anchor step by step:
1. Initial Position:
The anchor is 15⅗m below the surface.
2. Lowered:
- The anchor is lowered by 4⅕m.
- New position = Initial Position + Lowered Distance
- New position = 15⅗m + 4⅕m
3. Pulled Up:
- The anchor is pulled up by 19⅘m.
- Final position = New Position + Pulled Up Distance
- Final position = (15⅗m + 4⅕m) - 12⅗m
Calculate the position of the anchor:
1. Initial Position:
Initial position = 15⅗
2. Lowered:
New position after lowering = 15⅗ + 4⅕
3. Pulled Up:
Final position = 15⅗ + 4⅕ - 12⅗
Calculating each step:
1. Initial Position:
Initial position = 15⅗ = 15.6m
2. Lowered:
New position after lowering = 15.6 + 4⅕ = 15.6 + 4.2
= 19.8m
3. Pulled Up:
Final position = 19.8 - 12⅗ = 19.8 - 12.6 = 7.2m
Therefore, the anchor's new position is 7.2meters below the surface of the ocean.
