If a projector has a distance to screen width ratio of 2.0:1 and the screen is 10 feet wide, what is the estimated distance from the projector to the screen?

To determine the distance from the projector to the screen based on the given ratio and screen width, you start by applying the distance to screen width ratio of 2.0:1. This means that for every unit of width, the projector needs to be twice that distance away from the screen.

Given that the screen width is 10 feet, you multiply that width by the distance ratio. So, if the width of the screen is 10 feet, you calculate the distance as follows:

Distance = Width of screen × Distance to screen width ratio

Distance = 10 feet × 2.0 = 20 feet

This calculation shows that the correct estimated distance from the projector to the screen is indeed 20 feet, which aligns with the correct answer.
