I've managed to read the visual. Next time post a better visual that is not very blurry. Moving on to the problem.
First you must know that 1 mile = 1760 yards.
Dominic's trail is 6 miles long, which is equal to 10560 yards.
You can compare Dominic's trail, 10560, to Terell's trail, 7020.
10560 > 7020
Therefore, Dominic's trail is longer.<------
To find the difference, subtract.
10560 - 7020 = 3540
In yards, the difference is 3540.<-----------
3540 yards is the same as 2.01.
2.01 is the difference .<-----------
