Answer:

17 1/8 km

Step-by-step explanation:

6 7/8 + 5 1/2 + 4 3/4

The common denominator is 8

6 7/8 already has a denominator of 8

5 1/2 = 5 1/2*4/4 = 5 4/8

4 3/4 *2/2 = 4 6/8

6 7/8 + 5 4/8 + 4 6/8

15 17/8

15 + 8/8+ 8/8+1/8

15 + 1 + 1 + 1/8

17 1/8

Answer:

17⅛ km

Step-by-step explanation:

Total distance covered = sum of the two individual distances

= 6⅞ + 5½ + 4¾

= (6 + 5 + 4) + (⅞ + ½ + ¾)

= 15 + [7 + 1(4) + 3(2)]/8

(LCM of 8,2 and 4 is 8)

= 15 + (17/8)

= 15 + 2⅛

= 17⅛
