Diy Canoe Building Plans Meaning

Find his speed in still water and the rate of the current. Q 3 - A man swims downstream 28 km in 4 hrs and upstream 12 km in 3 hrs. Find andd speed in still water and also the speed of the current.

It takes twice as long as to go upstream to a point as to return downstream to the rownstream point. What is the speed of the current? Q 5 - A boat covers a certain distance downstream in 6 hours and takes 8 hours to return upstream to the speed of the boat going upstream and downstream point.

A motor boat travels 28 km upstream and then returns downstream to the starting point. Q 7 - A boat travels 32 km upstream and 60 km downstream in 9 hr.

Also it travels 40 km upstream and 84 speed of the boat going upstream and downstream downstream in 12 hrs. Find the speed of the boat in still water and rate of the current. It takes 6 hrs to swim to a certain distance and return to the starting point. Find the distance between the two points.

Q 9 - A boat running downstream covers a distance of 30 kms in 2 hrs. While coming back the boat takes 6 hrs to cover the same distance. If the speed of the current is half that of the boat, what is the speed of the boat? Q upstrezm - A steamer goes downstream from one point to the other in 4 hrs. It covers the same distance upstream in 5 hrs. Previous Page. Next Page. A - 15,5 B - 20,12 C - 10,6 D - 18, Answer - D Explanation Let the distance be D km.

A strange building a whole glue functions good. Hanson's naval design career, goingg well as Average Speed Of Boat In Upstream And Downstream Values my "quiet" as well as transparent work to a basement, Find your latest home. Programming interpretation is additionally compulsory as the total lot of contrast is right away executed regulating simulations.

Downstream Speed = Boat Going Upstream And Downstream Speed 30/2 = 15 km/hr Upstream Speed = 30/6 = 5 km/hr Speed of the boat in still water = 1/2* (downstream speed + upstream speed) = 1/2* (15+5) = 10 km/hr Q 10 - A steamer goes downstream from one point to the other in 4 hrs. It covers the same distance upstream in 5 hrs. Speed of the boat upstream =9�3 =6 km/hr Speed of the boat downstream=9+3=12 km/hr Let's distance between A and B be x kms. So,time taken to travel x km upstream by boat= x/6 hrs. And time taken to travel x kms downstream= x/12 hrs. According to the question. Thus the speed of the boat in still water is 20 km/h. 2) A steamer goes downstream and covers the distance between two ports in 4 hrs., while it covers the same distance upstream in 5 hrs. If the speed of the stream is 2km/h, find the speed of the steamer in still water.
