Answer

the elevation of the ending point is 440 ft. greater than the elevation of the starting point.

Step-by-step Explanation

The data given in the table is the elevation of the ending point (260 ft. above the sea level) and that of the starting point for the trail (180 ft. below sea level).

Note that the sea level is usually referred to as havin an elevation of 0 and the points above the sea level have positive elevations while the points below the sea level have negative elevations.

So,

The elevation of the ending point = 260 ft. above the sea level = +260 feet

The elevation of the starting point for the trail = 180 ft. below sea level = -180 feet

The question then asks us to find how much greater is the elevation of the ending point than the starting point for the trail.

This simply asks of us to find the difference in elevation of the ending point and the starting point.

The difference in elevation = +260 - (-180)

= +260 + 180

= 440 ft.

Hence, the elevation of the ending point is 440 ft. greater than the elevation of the starting point.

Hope this Helps!!!
