Question

a racetrack is 40 yards long. how many feet is that?
1 yard = 3 feet
40 yards = feet

Explanation:

Step1: Recall the conversion factor

We know that \( 1 \) yard is equal to \( 3 \) feet. So the conversion factor from yards to feet is \( 3 \) feet per yard.

Step2: Multiply the number of yards by the conversion factor

To find out how many feet are in \( 40 \) yards, we multiply the number of yards (\( 40 \)) by the number of feet in one yard (\( 3 \)). So the calculation is \( 40\times3 \).

Step3: Calculate the result

\( 40\times3 = 120 \).

Answer:

120
