The distance horizontally across the ground the he land from his initial position is 990 meters.
The slope of a line shows how steep the line is. The slope is calculated using the formula:
Slope = vertical rise / horizontal run
From the question, the slope is 1.7. Hence:
Slope = vertical rise / horizontal run
1.7 = 1683 m / horizontal run
Horizontal run = 990 meters
Hence, the distance horizontally across the ground the he land from his initial position is 990 meters.
