Difference of elevation?

Question

A ball field is 300 ft. long and requires a 1% for drainage. The elevation of the lower end of the field is 757 ft. What will the elevation be at the other end of the field

Answer 1

This is a poor question, because ball fields should not be higher at one end than the other.

Traditionally, football fields were 'crowned'--that is, higher at the centerline (which ran from one goal line to the other,) and sloping gently off toward the sidelines.

 

A person could solve this problem assuming a flat but tilted field, but that's not the way it would be, realistically.

You wouldn't want the offense having to go uphill in its fourth quarter attempt to break a tie score!
