Question

A car takes 4hrs to travel from Bangalore to Chennai whereas the flight takes only 30min to travel from Bangalore to Chennai. If the distance from Bangalore to Chennai by road is 400km and the air is 150km. Calculate the average speed and average velocity of flight and car. ( For flight, distance and displacement can be taken as equal)

Answer in the given order (in $km/hr$ ):

Find the Average Speed of Flight, Average velocity of Flight, Average speed of car, Average velocity of car respectively.

• A. 300 , 300, 37.5 , 100
• B. 300 , 37.5, 100 , 100
• C. 300, 300, 200, 100
• D. 300, 300, 100, 37.5

Answer 1

The correct option is D

300, 300, 100, 37.5

(Average Speed)_flight = 150/0.5 = 300 $km/hr$

(Average Velocity)_flight = 150/0.5 = 300 $km/hr$

(Average Speed)_car= 400/4 = 100 $km/hr$

(Average Velocity)_car = 150/4 = 37.5 $km/hr$
