A man rows to a place 48 km distant and comes back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is ............
Fighter planes $X$ and $Y$ are moving towards a target $ 'O'$ along two perpendicular paths, with equal speeds. $X$ starts from a point at a distance of $19\mathrm { km }$ from $^ { \prime } O ^ { \prime }$ and $Y$ starts from a point at a distance of $12\mathrm { km }$ from $ \mathrm '{ O } '.$ After $1$ minute, it was found that they were $13\mathrm { km }$ away from each other. What is the speed at which they are travelling. given that they start simultaneously?

A boy takes 20 minutes to reach the school at an average speed of 12 km/hour. If he wants to reach the school in 15 minutes, his average speed (in km/hour) will be
After travelling for 30 minutes a train meets an accident, due to which it has to stop for 45 minutes. Due to the accident its speed is also reduced to 2/3 of its former value and the train reaches its destination 1 hour 30 minutes late. Had the accident occurred 60 km later, the train would have reached 30 minutes earlier. The length of the journey is
