Explanation

Choice D is correct. Since $1$ yard is equal to $3$ feet, $64$ yards is equal to $64 yards left parenthesis StartFraction 3 feet Over 1 yard EndFraction right parenthesis$ , or $192$ feet. It follows that $64$ yards per second is equivalent to $192$ feet per second. Therefore, the object's speed is $192$ feet per second.

Choice A is incorrect. A speed of $61$ feet per second is equivalent to $StartFraction 61 Over 3 EndFraction$ , not $64$ , yards per second.

Choice B is incorrect. A speed of $67$ feet per second is equivalent to $StartFraction 67 Over 3 EndFraction$ , not $64$ , yards per second.

Choice C is incorrect. A speed of $94$ feet per second is equivalent to $StartFraction 94 Over 3 EndFraction$ , not $64$ , yards per second.
