Question

The length of a bus is 20m .how many buses is required to cover the distance of 1km if they stand in a queue on the road

Answer 1

Answer:

Given:

Time(t)= 100 s , distance (s)=1km= 1000m

Vb=10m/s          (relative speed with respect to the bus)

Velocity (V)=distance /time = 1000/100= 10m/s

Vs= velocity of scooter,  Vb=velocity of bus

V = Vs-Vb         (both bus & scooter are moving in the same direction)

10= Vs-10

10+10 = Vs

20=Vs

Vs=20m/s

--------------------------------------------------------------------------------------------

The velocity with which scooterist should chase the bus is20m/s

Hope this will help you...

Answer 2

Answer:

50 buses

Step-by-step explanation:

1km = 1000m

1 bus = 20m

to calculate the number of buses we need to divide = 1000÷20

= 50 buses will be required.
