Explanation:

Step1: Identify field length

In American football, the end zone is 10 yards long, and the goal post is at the back of the end zone. The ball is on the 30-yard line of the offensive team's side.

Step2: Calculate horizontal distance

The total length from the 30-yard line to the goal line (start of end zone) is $30$ yards, plus the 10-yard end zone to the goal post.
$30 + 10 = 40$

Answer:

40
