Question

during his first year as a pilot, rob flies 6,692 miles. he flies 16,429 miles the second year and 24,211 miles the third year. he wants to estimate how many more miles he flew in the third year than the first and second year combined. which shows one way rob could estimate?

Answer 1

First years flies = 6,692 miles ≈7000 miles.

Second year flies = 16,429 miles ≈ 16000.

Third year flies = 24,211 miles ≈ 24000

Total number of miles flies in first and second year = 7,000miles +16,000 miles

Number of more miles he flew in the third year than the first and second year combined = Number of miles flies in third year - Total number of miles flies in first and second year

Number of more miles he flew in the third year than the first and second year combined 24,000 - (7,000+16,000)

Therefore, 24,000 - (7,000+16,000) estimation of how many more miles he flew in the third year than the first and second year combined.
