Answer:

10 km

Step-by-step explanation:

The Angle formed by their travel is a right angled triangle (check attached picture) , hence we can apply Pythagoras rule :

Hypotenus = sqrt(opposite² + Adjacent²)

Hypotenus = distance hiked after lunch :

D = sqrt(6² + 8²)

D = sqrt(36 + 64)

D = sqrt(100)

D = 10 km
