Question

A hiker walks 4.30 km east, turns 90.0º due south and walks an additional 2.48 km. What distance did the hiker travel? *

24.64 km
6.78 km
1.82 km
4.96 km

Answer 1

6.78 km

Step-by-step explanation:

Length of path due east = 4.3km

Length of path south = 2.48km

Unknown:

Distance covered = ?

Solution:

The distance covered is the total length of path from start to finish. It takes cognizance of the turns and every direction moved.

Unlike displacement which only considers the net direction from start to finish, distance sums up the total path.

So;

Distance = 4.3km + 2.48km = 6.78km
