Mark is training for a mini triathlon he rode his bike 3/4 of a mile, ran 5/6 of a mile , and swam 10/12 miles each day for 7 days. what combined distance did mark exercise during the week?

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
