Answer:
311 yards, 1 foot and 3 inches.
Step-by-step explanation:
We know that 12 inches equals one foot.
We know that 3 feet equals one yard.
We will start adding up the inches, from these two quantities:
9 inches + 6 inches = 15 inches (but 12 inches equals one foot) = 1 foot and <u>3 inches.</u>
Now we will add up the feet considering we have now one extra foot from our previous sum.
2 feet + 1 foot + 1 foot = 4 foot (but 3 feet equals one yard) = 1 yard and <u>1 foot.</u>
Now we will add up the yards considering we have now one extra yard from our previous sum:
140 yards + 170 yards + 1 yard = <u>311 yards.</u>
So our final answer is: <u>311 yards, 1 foot and 3 inches. </u>
