Question

subtract:
1 mi 3,078 ft − 3,508 ft = □ mi □ ft

Explanation:

Step1: Convert mile to feet

We know $1$ mile $= 5280$ feet, so $1$ mi $3078$ ft $= 5280 + 3078 = 8358$ ft

Step2: Perform the subtraction

Subtract the two foot values: $8358 - 3508 = 4850$ ft

Step3: Convert back to mi and ft

Divide total feet by 5280: $4850 < 5280$, so miles = 0, remaining feet = 4850

Answer:

0 mi 4850 ft
