Answer 1

20%?

Answer 2

NO

Answer 3

by the end of the trip, all 5 tires have been equally worn.

if one tire has completed x miles, and five tires have completed 10000 miles, then each tire has completed 2000 (i.e. 20%) miles.

Answer 4

80% because each tire was rested for 2000 miles

Answer 5

You use 4 tires at a time. Total "tire-miles" is 40,000 shared over 5 tires = 8000
80%
