Question

look at the above attachment
15. A car travelling on a straight road moves with a
uniform velocity 4 m/s for a time T and with uniform
velocity 5 m/s for another time 2T. The average
velocity of the car is
(1) 14 m/s
(2) 10 m/s
3.14/3
4.9/5​

Answer 1

Explanation:

option 3 is correct

average velocity = (4*T +5*2T)/(T+2T)

= (14T)/(3T) = 14/3
