Answer:
Part A: The unit that would be best to describes the situations is to the mile
Part B: 4 significant figures
Part C: 1,450 miles
Part D: He is not correct
Step-by-step explanation:
Part A: By unit conversion, we have;
1 mile = 1,760 yards
Given that the distance from Ottawa, Canada to Jackson Mississippi is 2,552,000 yards it would best simplified into miles
Part B: The number of significant digits in the reporters estimate are the non-zero digits before the zeros in the number figure which are 2, 5, 5, and 2 or 4 significant figures
Part C: 2,552,000 yards = 2,552,000 yards/(1,760 yards/mile) = 1,450 miles
Part D: Given that the distance from Jackson to Tucson = 7,159,680 feet, we have;
1 mile = 5,280 feet
Therefore;
7,159,680 feet = 7,159,680 feet/(5,280 feet/mile) = 1,356 miles
Therefore, the claim that the distance from Jackson to Tucson which is 1,356 miles is further than the distance from Ottawa, Canada to Jackson Mississippi which is 1,450 miles is not correct because;
The distance from Jackson to Tucson 1,356 miles 1,450 miles which is the distance from Jackson to Ottawa
