Solution

To solve this problem, we need to follow these steps:

  1. First, we need to find out how many feet of film are used in 60 minutes. We do this by multiplying the rate of the film through the projector (378 feet per minute) by the length of the film (60 minutes).

    378 feet/minute * 60 minutes = 22680 feet

  2. Next, we need to convert feet to kilometers. We know that 1 foot is approximately equal to 0.0003048 kilometers. So, we multiply the length of the film in feet by this conversion factor to get the length in kilometers.

    22680 feet * 0.0003048 kilometers/foot = 6.91 kilometers

So, the length of the film is approximately 6.91 kilometers. Therefore, the answer is a. 6.91.
