Question

It is 260 km from Patna to Ranchi by air and 320 km by road. An aeroplane takes 30 minutes to go from Patna to Ranchi whereas a delux bus takes 8 hours. Find the average velocity of the bus.

Short Note

Solution

 Straight path distance from Patna to Ranchi = Displacement of the bus = 260 km 

\[\therefore \vec{V}_{avg} = \frac{260}{8} = 32 . 5 \text{ km } /h\]  (Patna to Ranchi)
