Question 1147893
.


            The answer of 336 miles by @josgarithmetic is ABSOLUTELY INCORRECT.


            It is incorrect,  because on the way @josgarithmetic made arithmetic errors in his post.


            See my correct solution and correct answer below.



<pre>
The distance is the average speed multiplied by average time, which is 5 hours 45 minutes = {{{5}}}{{{3/4}}} hours = {{{23/4}}} hours


    distance = {{{64}}} . {{{23/4}}} miles = {{{(64*23)/4}}} = 16*23 = 368 miles.
