Find the distance d. Assume that the ratio of d to 80 ft is the same as the ratio of 30 ft to 40 ft.

1 answer

Using the ratio proportion, we can set up the equation:

d/80 = 30/40

Cross-multiplying, we get:

d * 40 = 80 * 30

Simplifying:

d = (80 * 30)/40

d = 60 feet

Therefore, the distance (d) is 60 feet.
