R. Gupta Solutions for Exercise 1: EXERCISE

A man can row downstream at $14 km/hr$ and upstream at $9 km/hr$. Man's rate in still water is

The speed of a boat in still water is $2 km/hr$. If its speed upstream is $1 km/hr$, then speed of stream is

A boat goes $40 km$ upstream in $8$ hours and $36 km$ downstream in $6$ hours. The speed of the boat in standing water is

A man rows upstream $16 km$ and downstream $28 km$ taking $5$ hours each time. The velocity of the current is

A man can row at the rate of $9\frac{1}{3} km/hr$ in still water and he finds that it takes him thrice as much time to row upstream than the time taken to row downstream the same distance in river. The speed of the current is ?

A man can swim at the rate of $3 km/hr$ in still water. If the velocity of the stream is $2 km/hr$, the time taken by him to swim to a place $10 km$ upstream and back is?

The current of the stream runs at the rate of $4$ $km$ an hour. A boat travels for $6$ $km$ and come back to the starting point in $2$ hours. The speed of the boat in still water is ?

A boat moves upstream at the rate of $1$ $km$ in $10$minutes and moves downstream at the rate of $1$ $km$ in $6$ minutes. The speed of the current is
