Question

Bus is moving from latur to tuljapur at speed of $60km/hr$ and comes back with speed of $50km/hr$ fin d the average speed and avg velocity

Answer 1

lets consider $x=$ distance between latur to tuljapur

Bus moving from latur to tuljapur at the speed $60km/h$

$t_1=\frac{xkm}{60km/h}=\frac{x}{60}hr$

Bus come back to latur with speed $50km/h$

$t_2=\frac{x}{50}hr$

Average speed, $v_{avg}=\frac{Totaldistance}{Totaltime}$

$v_{avg}=\frac{2x}{\frac{x}{60}+\frac{x}{50}}$

$v_{avg}=\mathrm{54..54}km/h$
