Ms. Sue I do not understand this question. Mr. Chen drove his truck 9,438 miles last year. He drove his truck 12,917 miles this year. How much farther did Mr. Chen drive his truck last year?

you just subtract the two.. it is telling you he drove x miles in one year then x miles is another.. what is the difference

Thans Bobby for you help And God bless you

12,917

To find out how much farther Mr. Chen drove his truck last year, you need to calculate the difference between the number of miles he drove this year and the number of miles he drove last year.

Step 1: Subtract the number of miles Mr. Chen drove last year from the number of miles he drove this year.
12,917 - 9,438 = 3,479

Therefore, Mr. Chen drove his truck 3,479 miles farther last year.
