Question

1) 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 where as a deluxe bus takes 8 hours.f ind the average velocity of the plane

with explanation​

Answer 1

Answer:

Average speed of plane:

Average speed of plane:     Distance from Patna to Ranchi =260km Time taken =30min=30/60=0.5hrs

Average speed of plane:     Distance from Patna to Ranchi =260km Time taken =30min=30/60=0.5hrs     Average speed= Total distance/ Time =260/0.5=2600/5=520km/hr 

Average speed of plane:     Distance from Patna to Ranchi =260km Time taken =30min=30/60=0.5hrs     Average speed= Total distance/ Time =260/0.5=2600/5=520km/hr (B) Average speed of bus: Distance =320km, Time=8hrs,

Average speed of plane:     Distance from Patna to Ranchi =260km Time taken =30min=30/60=0.5hrs     Average speed= Total distance/ Time =260/0.5=2600/5=520km/hr (B) Average speed of bus: Distance =320km, Time=8hrs,     Average speed = Total distance/ time =320/8=40km/hr

Average speed of plane:     Distance from Patna to Ranchi =260km Time taken =30min=30/60=0.5hrs     Average speed= Total distance/ Time =260/0.5=2600/5=520km/hr (B) Average speed of bus: Distance =320km, Time=8hrs,     Average speed = Total distance/ time =320/8=40km/hr(C) Average velocity of Plane : 

Average speed of plane:     Distance from Patna to Ranchi =260km Time taken =30min=30/60=0.5hrs     Average speed= Total distance/ Time =260/0.5=2600/5=520km/hr (B) Average speed of bus: Distance =320km, Time=8hrs,     Average speed = Total distance/ time =320/8=40km/hr(C) Average velocity of Plane :       Average velocity= Displacement/time Displacement of plane =260km [ it is straight path] 

Average speed of plane:     Distance from Patna to Ranchi =260km Time taken =30min=30/60=0.5hrs     Average speed= Total distance/ Time =260/0.5=2600/5=520km/hr (B) Average speed of bus: Distance =320km, Time=8hrs,     Average speed = Total distance/ time =320/8=40km/hr(C) Average velocity of Plane :       Average velocity= Displacement/time Displacement of plane =260km [ it is straight path]       Displacement of plane=260/0.5=520km/hr and direction is from Patna to Ranchi straight.

Answer 2

Answer:

The average velocity of the plane is 520kmhr.

Step-by-step explanation:

A) Average speed of plane:

Distance from Patna to Ranchi =260km Time taken =30min=30/60=0.5hrs

Average speed= Total distance/ Time =260/0.5=2600/5=520km/hr

(B) Average speed of bus: Distance =320km, Time=8hrs,

Average speed = Total distance/ time =320/8=40km/hr

(C) Average velocity of Plane :

Average velocity= Displacement/time Displacement of plane =260km [ it is straight path]

Displacement of plane=260/0.5=520km/hr and direction is from Patna to Ranchi straight.

{D) Average velocity of bus=260/8=32.5km/hr and direction is from Patna to Ranchi straight.
