Let us assume a man travelled from a point A to a point B over a distance 'd'. After a while he travels the same distance back to point A.

Therefore, since his initial and final positions are the same, displacement is equal to zero, and the distance travelled is (d + d) = 2d, which is not zero.

Noelle walks from point A to point B at an average speed of 5 kilometers per hour. At what speed, in kilometers per hour, must N
Debora [2.8K]

Answer:

the speed at which Noelle walks from point B to A, v=7.5 kilometers per hour

Explanation:

In this question we have given

average speed for the entire trip,S = 6 kilometers per hour

Speed of Noelle while walks from point A to B= 5 kilometers per hour

Therefore, time taken by Noelle to walks from point A to B,t_{1}=\frac{d}{5}

Let us consider distance between A and B is d.

Therefore total distance covered in moving from point A to B and then moving back from point B to A, =d+d=2d

Let v be the speed at which Noelle walks from point B to A

Therefore time taken by Noelle to walks from point B to A,t_{2}=\frac{d}{v}

we know that average speed S is given as

S=\frac{x}{t}................(1)

here, x (=2d) is total distance

and t (=t_{1}+t_{2} ) is total time

put values of S, x and t in equation 1

6 =\frac{2d}{\frac{d}{5}+\frac{d}{v}  }

on solving we get,

v = 7.5 kilometers per hour

Therefore, the speed at which Noelle walks from point B to A, v=7.5 kilometers per hour
