Answer:
0.35 feet per second
Step-by-step explanation:
To start, there's 3 feet in 1 yard.
So, we have to convert the 7 yards per minute to feet.
7 x 3 = 21
Then, we have to convert 21 feet per minute to X amount of feet per second.
To note, there are 60 seconds in a single minute
Therefore, you have to divide 21 by 60 to find the amount of feet in one second.
21 / 60 = 0.35
The answer is 0.35 feet per second
