Question

a hiker walks 11km due north from camp and then turns and walks 11 km due east. What is the approximate displacement of the hiker from the camp?

Answer 1

`d=11\sqrt2\ km`

Step-by-step explanation:

Given that,

Displacement in North = 11 km

Displacement in East = 11 km

We need to find the approximate displacement of the hiker from the camp. It can be calculated by resultant of two displacement as follows :

`d=√(11^2+11^2)\\\\= 11\sqrt2\ km`

Hence, the approximate displacement of the hiker from the camp is
`11\sqrt2\ km`.
