Question

A car takes 4 hours to travel from Bangalore to Chennai whereas the flight takes only 30 minutes to travel from Bangalore to Chennai. If the distance from Bangalore to Chennai by road is 400 km and the air is 150 km, calculate the average speed and average velocity of the flight and car.

Answer in the given order (in $\frac{km}{hr}$ ):

Find the Average speed of flight, average velocity of flight, average speed of car, average velocity of car.

• 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 $\frac{km}{hr}$

(Average Velocity)_flight = 150/0.5 = 300 $\frac{km}{hr}$

(Average Speed)_car= 400/4 = 100 $\frac{km}{hr}$

(Average Velocity)_car = 150/4 = 37.5 $\frac{km}{hr}$
