Final answer:
The IMAX camera uses film at a rate of 336 feet per minute. A 500-foot roll of film would be exhausted in about 89 seconds.
Explanation:
The rate at which the IMAX camera uses film can be determined by simple conversions. First, let’s move from feet per second to feet per minute. Given that 1 minute contains 60 seconds, we can multiply 5.6 ft/s * 60 s/min = 336 ft/min. That's the answer to question (a).
For question (b), we ought to find out how long a 500-foot roll of film will last. Given that the camera uses film at a rate of 5.6 feet per second, we use the formula Time=Distance/Speed. Substitute 500 feet for Distance, and 5.6 ft/s for Speed. So Time = 500 ft / 5.6 ft/s ≈ 89.286 seconds. Rounded to the nearest second, our answer is 89 seconds.

Answer:
a. To find the rate per minute, we need to convert the rate from feet per second to feet per minute:
5.6 ft/s * 60 s/min = 336 ft/min
Therefore, the camera goes through film at a rate of 336 feet per minute.
b. The camera uses 500 feet of film at a rate of 336 ft/min, so we can use the formula:
time = distance/rate
where the distance is 500 feet and the rate is 336 ft/min.
time = 500 ft / 336 ft/min
time ≈ 1.49 min
To convert minutes to seconds, we can multiply by 60:
1.49 min * 60 s/min ≈ 89.4 s
Therefore, the camera uses a 500-foot roll of 65-mm film in approximately 89 seconds.
