A boat p is moving at 40 km/hr. In one hour a boat goes 13 kmhr in the direction of the stream and 7 kmhr against the direction of the stream. Instead of using mph for the equation you need to convert your speed into knots which is nautical miles per hour. Give the components of the velocity vector of a boat which is moving at 40 kmhr in a direction 20 degrees south of west.

A boat goes 12 km upstream and 40 km downstream in 8 hrs. By what angle does the current push the boat off its due east course. Sound moves through the air at a speed of around 343 meters per second which is 12348 kmh or 767 mph at.

Answer with proper explanation. A boat P is moving at 40 kmhr and another boat Q is moving at 20 kmhr. 1 milehour 0868976 knots kts.

As the boat is moving with the velocity of the stream xv 27 13 it goes 40kmhr As the boat is moving against the stream x-v 27 - 13 it is going 14 kmhr. The time it takes for the light from the Sun to reach the Earth is around 8 minutes. Also if the downstream speed is a kmhr suppose and the speed upstream is b kmhr then.

Your answer should be a positive angle less than π. Find the speed of the stream. A person rowing at the rate of 5 kmhr in still water takes thrice as much time in going 40 km upstream as in going downstream.

The speed of the boat in still water in kmhr. Which one of the following is not a possible value for their relative velocity 1 10 kmhr 2 20 kmhr 3 30 kmhr 4 40 kmhr Q37. The relative velocity of the rain is 1 13kmhr 2 7kmhr 3 109kmhr 4 13 kmhr Q36.
