Question

A car travels 40km from Delhi to Noida in half an hour towards east. It comes back from Noida to Delhi in another half an hour. Calculate the speed and velocity. ​

Answer 1

Explanation:

Delhi•_____________________•Noida -> East

⁴° km

Given That,

• Distance = 40+40Km = 80km
• Time Taken= 0.5+0.5Hr = 1 Hrs

To Find

1. Speed = ?
2. Velocity = ?

Now

$speed = \frac{distance}{time}$

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

So

• Speed = 80/1= 80kmh-¹
• Velocty=0/1=0kmh-¹
