<strong>Explanation:</strong>
|
||
|
|
Elvis and Lee traveled 450 miles, Elvis is the top traveler as his name is alphabetically smaller than Lee.
|
||
|
|
Bob, Jonathan, Alex, and Alice have only one ride and we just order them by the total distances of the ride.
|
||
|
|
Donald did not have any rides, the distance traveled by him is 0.
