To answer this question, we can graph the situation as follows:

We can find the distance between the top of a mountain and the bottom of its valley subtracting both numbers. Since we have integers of different signs, we can proceed as follows:


\begin{gathered} D=1240ft-(-620ft) \\ D=1240ft+620ft \\ D=1860ft \end{gathered}

We subtracted the lowest point from the highest point.

In summary, therefore, we have that the distance between the top of the mountain and the bottom of the valley is 1860ft.
