Answer:

$\Huge{\textbf{\textsf{{\purple{Ans}}{\pink{wer}}{\color{pink}{:}}}}}$

Given:-

• Displacement in North Direction ,S1 = 50 m
• Displacement in South Direction ,S2 = 30 m

To Find:-

Total displacement of the runner ,S

Solution:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀According to the Question

It is given that the runner travels 50 m in the North Direction & 30 m in South Direction . If we consider the North Direction as original direction . Then , we take the displacement of South direction as negative.

• Displacement is defined as the shortest distance between two points .

☯ Total Displacement = Displacement in North - Displacement in South

Substitute the value we get

:⟹ Total Displacement = S1 - S2

:⟹ Total Displacement = 50-30

:⟹ Total Displacement = 20 m

Hence, the total displacement of the runner is 20 metres .

Answer 2

Answer :

the total distance she ran is 80 m.

total displacement of the runner is 20 metres
