Question

7. A body travels towards north with velocity 2 m/s for 20 s and then moves
towards east with velocity 3 m/s for 10 s. Its average velocity is
a) 2.5 m/s b) 5/3 m/s c) 7/3 m/s d) 50/3 m/s
8.

Answer 1

Answer:

$\huge\boxed{\fcolorbox{red}{pink}{Your's Answer}}$

$average \: velocity = \frac{total \: distance}{total \: time}$

Total distance= 40m+ 30m

= 70m

Total time= 20s+ 10s

=30s

According to question:

$= \frac{40 + 30}{20 + 10}$

$= \frac{70}{30}$

$= \frac{7}{3}$
