Final answer:
Mr. James traveled 1,000 miles more in the second year than in the first year, calculated by subtracting 9x10³ miles (9,000 miles) from 1x10´ miles (10,000 miles).
Step-by-step explanation:
The student is asking how many more miles Mr. James traveled in the second year than he did in the first year. Mr. James traveled 9x10³ miles in the first year and 1x10´ miles in the second year. To find the difference, subtract the first year's mileage from the second year's mileage:
1x10´ miles (second year)
-
9x10³ miles (first year)
= 1x10´ miles - 9x10³ miles.
Since 1x10´ is the same as 10,000 and 9x10³ is the same as 9,000, we can simplify the subtraction to:
10,000 miles (second year)
-
9,000 miles (first year)
= 1,000 miles.
Therefore, Mr. James traveled 1,000 miles more in the second year than he did in the first year.
