Question 1
A man can row 30 km downstream and return to the starting point in 8 hours. If the speed of the boat in still water is four times the speed of the current, then the of the speed current is
Question 2
A boat travels 24 km upstream in 6 hours and 20 km downstream in 4 hours Then the speed of boat in still water and the speed of current water are respectively
Question 3
If a boat goes 100 km down stream in 10 hours and 75 km upstream in 15 hours, then the speed of the stream is
Question 4
A man rows 40 km upstream in 8 hours and a distance of 36 km downstream in 6 hour Then speed of stream is
Question 5
The speed of a boat in still water is 10km/hr. It covers upstream a distance of 45 km in 6 hours. The speed (in km/hr) of the stream is
Question 6
Amit rows a boat 9 kilometres in 2 hours down-stream and returns upstream in 6 hours. The speed of the boat (in kmph) is:
Question 7
Rajesh rows in still water with a speed of 4.5 kmph to go to a certain place and comes back. Find his average speed for the whole journey, if the river is flowing with a speed of 1.5 kmph?
Question 8
A boat travels 24 km upstream in 6 hours and 20 km downstream in 4 hours. What is the speed of a boat in still water and the speed of current respectively?
Question 9
P, Q and R are the three towns on the bank of a river which flows uniformly. Q is equidistant from P and R. I row from P to Q and back in 10 hours and I can row from P to R in 4 hours. Compare the speed of my boat in still water with that of the river.
Question 10
A man can cross a downstream river by steamer in 40 minutes and the same river by boat in 1 hour. If the time taken for crossing the river in upstream direction by steamer is 50% more than the downstream time by the steamer and the time required by boat to cross the same river upstream is 50% more than that required downstream by boat, then what is the time taken by the man to cross the river downstream by steamer and then return to same place by boat half the way and by steamer the rest of the way?
