If you travel from mile 100 to mile 324, you will have traveled how many miles?

• A. 100
• B. 324
• C. 424
• D. 224

Answer: (D)

On a highway, the distance you travel between two mile markers is the difference between those markers. Starting at mile 100 and ending at mile 324 means you’ve moved forward 324 minus 100 miles. That equals 224 miles. The mile markers count up as you go, but you don’t add an extra mile for the starting point—you’re measuring the length of road you covered. If you traveled in the opposite direction, you’d still cover 224 miles, just in the other direction.
