Question

While traveling along a highway a drivers velocity is 9m/s. In 12 seconds how far has the car gone?

Answer 1

While travelling along a highway a drivers velocity is 9 m/s. In 12 seconds, the car has gone for 108 m.

Explanation:

The car travelling along the highway has a uniform velocity of 9 m/s. therefore to calculate the distance travelled by the car with the uniform velocity in 12 seconds, simple formula of velocity is to be employed.

Thereby, as we know that

           $\text {velocity}=\frac{\text {displacement}}{\text {time}}$

The displacement is along the highway with uniform motion, therefore, distance=displacement

Given that,

Velocity = 9 m/s  

Time = 12 s

Putting the values in the formula, we get,

       $9 = \frac{d}{12}$

       $d=12 \times 9=108 \mathrm{m}$

Therefore, the car travels for 108 m in the 12 seconds while travelling along highway with 9 m/s of velocity.
