Answer:
52.8 Kmph
Step-by-step explanation:
Let us first find the distance covered by the bus
2 x 0.56 x 22/7 x 250
When we solve this we get 880 meters
In a minute there are 60 seconds
Therefore the speed in mps (meters per second) is 880/60
When we reduce it is 44/3
Let us now convert this in Kmph 44/3 x 3600/1000
When solved 52.8 kmph
