Velocity

#### Explanation:

Calculating the upper and lower bound helps you in this type of problem.

If the body travels the longest distance (

time (

of the velocity

Simirally, the lower bound of the velocity

Therefore, the velocity

Option (b)

#### Explanation:

if the Quantity is defined as

let

then The Maximum Possible Relative Error in **x** is

Now

Distance

Time

Velocity of Body Within error Limit is

Now

and Relative error in Velocity

Absolute Error in Velocity

Hence

Velocity of Body Within error Limit is

Option (b)

Hope You gets your answer.
