Leanna's grandfather has a routine of driving his truck over the course of the week, and the task at hand is to calculate the difference in the total mileage driven between two consecutive weeks. Last week, he covered a distance of 352 miles on Monday and 249 miles on Tuesday. On Wednesday, he drove 154 miles less than what he did on Monday. To find out the distance travelled on Wednesday, we subtract 154 from Monday's mileage: 352 miles - 154 miles = 198 miles. Summing up the mileage for the three days last week gives us a total of 352 miles + 249 miles + 198 miles = 799 miles.

This week, Leanna's grandfather drove a total of 782 miles. To find the difference in mileage between the two weeks, we compare the totals. Subtracting this week's total from last week's gives us 799 miles - 782 miles = 17 miles. Therefore, the difference in mileage between this week and last week is 17 miles, indicating that Leanna’s grandfather drove 17 miles more last week than he did this week.
