Final answer:
3.39 feet per minute is equivalent to 0.424 yards per second. Option C.
Step-by-step explanation:
To convert feet per minute to yards per second, we use the following formula:
ft/min ÷ 5280 = yd/s
Where 5280 is the number of feet in one mile and one mile is equivalent to 1760 yards.
In this case, we have 3.39 feet per minute, which is equivalent to:
0.424 yards per second (rounded to two decimal places)
To calculate this, we divide 3.39 by 5280 and then multiply by 1760:
0.000647 yards per second (rounded to 12 decimal places)
Then, we round this value to two decimal places to get our final answer: 0.424 yards per second.
