Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:

In a race of 200m, A can beat B by 31 m and C by 18 m. In a race of 350m, C will beat B by:

A man rows downstream at 32 km and 14 km upstream at 13kmph.the speed of the stream is:

325-(12)² + 75= (?)²-68

A boat covers a certain distance downstream in 1 hour, while it comes back in 1 ½ hours. If the speed of the stream be 3 kmph. What is the speed of the boat in still water?

At what approximate time between 4 and 5 am will the hands o f a clock be at right angle?

A man’s speed with the current is 15 km/hr and the speed of the current is 2.5kmph, the man’s   Speed against the current is
