The distance from Patna to Ranchi is

260 \text{ km}

by air and

320 \text{ km}

by road. An aeroplane requires

30

minutes to travel from Patna to Ranchi, while a delux bus takes

8

hours. Determine the average speed of the plane in km/h.

Options

A $130$
B $520$
C $260$
D $640$

Correct answer

B. $520$

Step-by-step solution

Distance covered by the aeroplane,

d = 260 \text{ km}

Time taken by the aeroplane,

t = 30 \text{ minutes} = \dfrac{1}{2} \text{ h}

Average speed of the plane

= \dfrac{d}{t}

Average speed

= \dfrac{260}{1/2} = 520 \text{ km/h}
