How long does it take a boat to travel 24 km upstream?

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 are respectively. A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream.

What is the speed of boat in still water?

8). Speed of a boat is 5 km per hour in still water and the speed of the stream is 3 km per hour. If the boat takes 3 hours to go to a place and come back, the distance of the place is : 9). A boat covers 12 km upstream and 18 km downstream in 3 hours, while it covers 36 km upstream and 24 km downstream in 6 1 2 hours.

How many miles can a boat travel in 4 hours?

SOLUTION: a boat travels 24 miles upstream in 4 hours.going downstream,itcan travel 64 miles in the same amount of time. Find the speed of the current and the speed of the boat in still wate SOLUTION: a boat travels 24 miles upstream in 4 hours.going downstream,itcan travel 64 miles in the same amount of time.

How long does it take to travel 30 km downstream?

A motorboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. The speed of the stream (in km/hr) is:

How fast can a person row in still water?

6). A person can row 7 1 2 km an hour in still water and he finds that it takes him twice as long to row up as to row down the river. The speed of the stream is:

How long does it take to row 30 km down stream?

5). A man can row 30 km down stream and return in a total of 8 hours. If the speed of the boat in still water is four times the speed of the current, then the speed of the current is:

How fast does a current run in a stream?

3). The current of a stream runs at the rate of 4 km an hour. A boat goes 6 km and comes back to the
