Question

a bus covers 100 KM at uniform velocity of 50 km per hour and then next 100 KM at 75 km per hour find the average velocity of the bus​

Answer 1

Hello!

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

Time = distance/speed

= 100/50

=2 hours

Time = distance/speed

=100/75

=4/3

=1.3

Hence

Avg. Velocity = 100+100/2+1.3

=

$\frac{200}{3.3} \\ = > 60.60$

Hence average velocity = 60.60 m/s

The question has not given if the bus is travelling on a straight road or not.

In this solution, I have assumed that the bus travelling on a straight road.

hope this helps.

Answer 2

Average velocity =Total displacement /Total time taken therefore, total displacement =(100+100)km=200km                       total time=(2+0.75)hour =2.75hour                                         so, average velocity =200/2.75km/hr         =72.7km/hr
