Final answer:
To determine how many yards there are in 1 mile, divide the total feet in a mile (5280) by the number of feet in a yard (3), which results in 1760 yards in 1 mile.
Step-by-step explanation:
The function Y(x) = 1/3x allows us to convert from feet to yards. To find out how many yards are there in 1 mile, we use the given information that there are 5280 feet in 1 mile. Since 1 yard is equal to 3 feet, we divide the total number of feet in 1 mile by 3 to get the number of yards.
To calculate:
Start with 1 mile = 5280 feet.
Since 1 yard = 3 feet, to convert feet to yards, divide the number of feet by 3:
5280 feet ÷ 3 feet/yard = 1760 yards in 1 mile.
Therefore, there are 1760 yards in 1 mile.
