Answer:

  • The Displacement of the cyclist is 5 Km.
  • The Distance of the cyclist is 7 Km.

Given:

  1. A B Length = 4 Km.
  2. B C Length = 3 Km.

Explanation:

#Refer the attachment for figure.

Displacement:

It is a Shortest path between Initial and Final position of the body.

Now, in the given in Figure,

The shortest path is A C

Applying, Pythagoras theorem,

AC² = AB² + BC²

Substituting the values,

⇒ AC² = (4)² + (3)²

⇒ AC² = 16 + 9

⇒ AC² = 25

⇒ AC = √ 25

⇒ AC = 5

AC = 5 Km

Displacement = AC = 5 Km.

The Displacement of the cyclist is 5 Km.

\rule{300}{1.5}

\rule{300}{1.5}

Distance:

The total length of the path covered by the body during its travel.

Now, in the given figure,

Distance is sum of AB and BC

Distance = AB + BC

Substituting the values,

⇒ Distance = 4 Km + 3 Km

⇒ Distance = 4 + 3

⇒ Distance = 7

Distance = 7 Km

The Distance of the cyclist is 7 Km.
