Question

a boy walks 4 km towards east then turns right and walks another 3km towards south, find the distance and displacement​

Answer 1

Answer:

distance traveled is 7km

displacement is not defined as your question has error as hypotenuse is the longest side but in ur case the hypotenuse is 3 instead of 4

taking the hypotenuse as 4

and base as 3

the displacement will be √7 kms

Answer 2

The total distance and displacement of the boy are 7km and 5km respectively.

Given:-

Distance moved by boy in East = 4km

Distance moved by boy in South = 3km

To Find:-

The total distance and displacement of the boy.

Solution:-

We can easily find out the total distance and displacement of the boy by using these simple steps.

As

Distance moved by boy in East = 4km

Distance moved by boy in South = 3km

According to the formula,

Total distance covered = distance in East + distance in South

Total distance covered = 4 + 3 = 7km

Now, Displacement = shortest path

Since both the directions are at right angle from each other,

(Displacement)² = 4² + 3²

d² = 16 + 9

d² = 25

d = √25

d = 5km

Hence, The total distance and displacement of the boy are 7km and 5km respectively.
