A 13 kmhr B 8 kmhr C 7 kmhr D 11 kmhr E 16 kmhr.

A boat covers 25 km upstream. Those who dint know typing because you cant remove from who know shorthand. 25-1015-So 15 people dont know typing now so they have to know short hand. Average Speed of Boat Upstream Speed Downstream Speed Boats Speed in Stii Water If it takes t hours for a boat to reach a point in still water and comes back to the same point then the distance between the two points can be calculated by Distance u 2 -v 2 t 2u where u is the speed of the boat in still water and v is the speed of the stream.

Speed of a boat in upstream x - y kmhr and. Also it covers 15 km upstream and 22 km downstream in 5 hours. A motorboat covers 25 km upstream and 39 km downstream by travelling at the same speed for 8 hours.

How much time will the boat take to cover 15 km upstream. Also it covers 15 km upstream and 22 km downstream in 5 hours. A boat covers 12 km upstream and 18 km downstream in 3 hours while it covers 36 km upstream and 24 km downstream in Large 6frac12 hours.

At the same speed it can travel 35 km upstream and 52 km downstream in. Are solved by group of students and teacher of Class 10 which is also the largest student community of Class 10. Determine the speed of the stream and that of the boat in still water.

The Questions and Answers of A boat travels 25 km upstream and 44 km downstream in 9 hours also it covers 15 km upstream and 22 km downstream in 5 hours. Vv35V-v25 after solving we get V30 v5 So speed of current v5kmh. A boat covers 25 km upstream and 44 km downstream in t hours.

Relative speed 20 5kmhr 25 kmhr. A boat covers 24 km upstream and 36 km downstream in 6 h while it covers 36 km upstream and 24 km downstream in 6frac12 h. Question 36 A motorboat covers a distance of 16km upstream and 24km downstream in 6 hours.
