Question

Two buses A ans B are moving in opposite direction with the velocity of 36km/hr and 108km/hr. Find the relative velocity of A with respect to B and total displacement between them after 60 seconds.​

Answer 1

Answer:

Suppose total distance is 2x km then

time taken in traveling the distance first x will be t

1

=

40

x

and the time taken in traveling the distance second x will be t

2

=

60

x

now the average velocity can be calculated as V=

total time

total distance

=

40

x

+

60

x

2x

=

40+60

2×40×60

=48Km/h
