Answer: 7,040 yards
Step-by-step explanation: In this problem, we are asked to convert 4 miles into yards. Unfortunately, we don't have a conversion factor for miles and yards but we do have conversion factors we can work with.
Conversion factors
5,280 feet = 1 mile
3 feet = 1 yard
We can convert 4 miles into yards by using both of these conversion factors.
Let's first convert 4 miles into feet. Remember that when we go from a larger unit "miles" to a smaller unit "feet" we multiply. We can convert 4 miles into feet by multiplying 4 by the conversion factor which is 5,280 and we will get 21,120 feet.
Next, we convert feet to yards. When we convert feet to yards we are now going from a smaller unit to a larger unit so we divide 21,120 by the conversion factor which is 3 to get 7,040 yards.
Therefore, 8 miles = 7,040 yards.
