Question

The buses are deported after every 20min but man going away from the bus deport after every 24 min get the buses find the speed of buses if the speed of man is 30 km per hour​

Answer 1

Step-by-step explanation:

Let Speed of the man is x kmph.

Distance covered in 10 minutes at 20 kmph = distance covered in 8 minutes at (20 + x) kmph.

Or, 20×1060=860×(20+x)

Or, 200 = 160 + 8x

Or, 8x = 40

Hence, x = 5kmph.

Answer 2

Answer:

5 km/hr

Step-by-step explanation:

Bus : (Bus + Man)

Ratio of Time = 10 min : 8 min

Ratio of Speed = 8 : 10

= 4 : 5

= 4 : 4+1

Here, 4 unit = 20 kmph

1 unit = 5 kmph

∴Speed of the man

= 1 unit

∴Speed of the man

= 1×5 = 5 km
