You walk forward 10 meters, backwards 5 meters, and then 10 meters forwards in 15 seconds. what is your overall velocity forwards in m/s?

Overall velocity of a person is 1.66

Explanation:

Let the forward displacement of the person is taken as positive and backward displacement is taken as negative.

You walk forward 10 meters,

displacement = = 10 meter

You walk backward 5 meters,

displacement = = -5 meter

You walk forward 10 meters,

displacement = = 10 meter

Total displacement = s =

s = 15 -5 +15

s = 25 meter

Total time taken is given by,

t = 15 second

Overall velocity is the average velocity of a person and it is given by,

Average velocity =

Average velocity =

Average velocity = 1.66

Thus, overall velocity of a person is 1.66

The overall velocity is 1 m/s .

Explanation:

Given that,

He walk forward 10 meter, 5 m backward and then 10 m forward.

Time = 15 sec

We need to calculate the total distance

We need to average velocity

Using formula of average velocity

Where, D = total distance

T = total time

Put the value into the formula

Hence, The overall velocity is 1 m/s .
