So I started off by subtracting 1422 with 1016, then 1016 with 1202 and so forth... but I end up with the wrong answer? I don't understand what I'm doing wrong...

 

The right answer is 1743 miles and I got 1753 miles

Using absolute value to determine distance

 

 

\(\begin{array}{|rcll|} \hline && (1422-1016)-(1016-1202)+(1202-918)+(918-496)+(496-51) \\ &=& 406 + 186 + 284 +422 +445 \\ &=& 1743 \\ \hline \end{array}\)

Sorry, I don't understand why the distance between Delta Junction and Haines Junction is subtracted with the distance between the two destinations travelled on Thursday?

Because 1016 -1202 = -186  is negative. Using the absolute value is -(-186) = + 186
