Question 61 Hard

The current of a stream at 1 kmph. A motor boat goes 35 km upstream and back to the starting point in 12 hours. The speed of the motor boat in still water is?

Question 62 Hard

man whose speed is 4.5 kmph in still water rows to a certain upstream point and back to the starting point in a river which flows at 1.5 kmph, find his average speed for the total journey?

Question 63 Hard

The current of a stream runs at the rate of 4 kmph. A boat goes 6 km and back to the starting point in 2 hours, then find the speed of the boat in still water?

Question 64 Hard

A man can row 6 kmph in still water. When the river is running at 1.2 kmph, it takes him 1 hour to row to a place and black. What is the total distance traveled by the man?

Question 65 Hard

A man can row 6 kmph in still water. When the river is running at 1.2 kmph, it takes him 1 hour to row to a place and black. How far is the place?

Question 66 Medium

A man swims downstream 72 km and upstream 45 km taking 9 hours each time; what is the speed of the current?

Question 67 Medium

A man swims downstream 30 km and upstream 18 km taking 3 hours each time, what is the speed of the man in still water?

Question 68 Medium

A boat can move upstream at 25 kmph and downstream at 35 kmph, then the speed of the current is?

Question 69 Medium

A man can row upstream at 25 kmph and downstream at 35 kmph, and then find the speed of the man in still water?
