Final answer:
To calculate the speed of the equipment in feet per second, first we convert 16.8 yards to 50.4 feet and then divide that by 720 seconds to get 0.07 feet per second.
Step-by-step explanation:
To find out how many feet the equipment moves per second, we need to perform a few conversions. First, convert the initial distance from yards to feet, and then divide that by the total number of seconds.
There are 3 feet in a yard, so we multiply the distance of 16.8 yards by 3 to convert to feet:
16.8 yards * 3 feet/yard = 50.4 feet
There are 60 seconds in a minute, so there are 12 minutes * 60 seconds/minute = 720 seconds in 12 minutes.
Next, we divide the total distance in feet by the total number of seconds to find the speed:
50.4 feet / 720 seconds = 0.07 feet per second
This is the speed at which the equipment moves.
