Q1. A this usual rowing rate Mohit can travel 12 miles downstream in a certain river in 6 hours less than it takes him to travel the same distance upstream But if he could double his usual rowing rate for his 24 miles round trip the downstream 12 miles would then take only one hour less than the upstream 12 miles What is the speed of the current in miles per hour

Q2. A boat goes 20 km downstream in one hour and the same distance upstream in two hours The speed of the boat in still water is

Q3. A boat goes 12 km downstream and comes back to the starting point in 3 hours if the speed of the current is 3 km hr then the speed of the boat in still water is

Q4. A boat goes 6 km an hour in still water it takes thrice as much time in going the same distance against the current comparison to direction of current The speed of the current in km hour is

Q5. A man can row 9 3 5 km hr in still water and he finds that it takes him twice as much time to row up than as to row down the same distance in river The speed km hr of the current is
