## Answer

## General guidance

The total distance travelled by the particle is, Here, is the total distance travelled by the particle, is the final position of the particle and is the initial position of the particle. The average velocity of the particle is, Here, is the average velocity, and is the time taken by the particle.

## Step-by-step

### Step 1 of 3

(1) The expression for the travelled distance is, Substitute forand for

The travelled distance by the particle is.

The travelled distance by the particle is calculated by subtracting the initial position from the final position.

### Step 2 of 3

(2) The expression for the average velocity is, Substitute for, 50s for

The average velocity for the particle is.

The average velocity of the particle is calculated by substituting the total distance and time in the kinematics equation.

### Step 3 of 3

(3) The expression for the instantaneous velocity is, Substitute for.

The instantaneous velocity of the particle is

The instantaneous velocity of the particle is equal to the average velocity as the particle is moving with a constant velocity.

### Answer
