Find its average speed.A man travels the first half of a journey at $30$ km/hr and the second half at $60$ km/hr. Find his average spIf the ratio of the speeds of A and B is $3 : 4$, what is the ratio of the times they take to cover the same dA train $150$ m long is moving at $54$ km/hr. How long will it take to completely cross a platform $250$ m lonTwo trains start at the same time from stations A and B, which are $600$ km apart, moving towards each other aFor a fixed distance, if the speed is increased then the time taken:A journey takes 120 km at a steady 60 km per hour.
