A footbridge is being built across the river that will connect points A and B. If the length of each box represents 2 yards, approximately what will the length of the footbridge be?

To determine the length of the footbridge, we need to calculate the distance between points A and B using the given scale of 2 yards per box.

Let's assume the number of boxes between points A and B is 5.

Therefore, the approximate length of the footbridge would be:
5 boxes * 2 yards/box = 10 yards

So, the approximate length of the footbridge would be 10 yards.
