Select an option to attempt

Explanation

Allowed roads (and their lengths along straight grid lines): CD: from D to C → length = 66 km CA (same as AC): from C to A → length = 1010 km AB: from A to B → length = 66 km BF: from B to F → length = 99 km

Q55

Q55

A connected route from D to F using only the given roads is: D → C → A → B → F

Total distance = DC + CA + AB + BF = 6+10+6+9=316 + 10 + 6 + 9 = 31 km

Therefore the distance covered = 3131 km (Option C).
