Multiple choice

The height of building A is 20 feet and the distance between the foot of building A and a car is 16 feet. The height of building B is 25 feet and the distance between the foot of the building and a bus is 'd'. If the distances are proportional to the heights of the buildings, then what would be the value of 'd', in feet?

D Correct answer
Explanation

Since the distances are proportional to the heights, we set up the ratio 20/16 = 25/d. Solving for d gives 20d = 16 * 25, which is 20d = 400, so d = 20.

AI explanation

The problem states that the distances are proportional to the heights of the buildings. We set up the proportion 16 / 20 = d / 25 using the given heights and distances. Solving for d involves cross multiplying to get 20 d = 400. Dividing by 20 yields d = 20 feet.
