Since we have to find the least possible distance traveled by a car with most mileage, lets start with the smallest option and see whether it satisfies the conditions
A-60,001
Now, other cars can have traveled 60,000 and 59,999 (total=180,000)
This satisfies the condition (distance traveled by each car differs by at least 1 mile), so this is the answer

Ans:A
