Upstream is B - S.

A yacht travels 88 kilometers. On the way back downstream the trip only takes 45 hours. The total EW distance is 8 - 2 6 kmThe total NS distance is 5 kmTherefore total distance from the start is sqrt62 52 sqrt36 25 sqrt61 78 km approxThe answer assumes that the boat is sufficiently far from the poles so that the various stages of its travel is along perpendicular linesThe total EW distance is 8 - 2 6 kmThe total NS distance is 5 kmTherefore total. Boat speed 34kmh current speed 8kmh Of course after you find the upstream and downstream speeds you can find the boat speed and current speed with formal algebra.

12 BC 12 10C 2 C. Now we have the data that we will need to determine our burn rate. Distance km 128 64 32 8 72 Time hr 4 2 1 1_ 4 2_ 1 4 Solution.

At this rate how far did the boat travel in 2 hours and 15 minutes. If the rate of stream be 5 kmph find the speed of the boat in still water. Find the total time taken by a man rowing to a place at a distance of 88 km and back.

50 min 710 pm. The last part of the equation is to subtract the travel time by boat from the time the party starts. An 8-knot cruising speed allows the 58E to travel a little over 1400 nautical miles.

Now lets do the math 35 gallons at 2 hours is 175 gallons per hour round up 180 gallons per hour. Generally a motorized yacht about 35 feet in length can travel around 200 miles at approximately 25 knots in an 8 hour day. Rate Time Distance.

And as it travelled 210 miles upstream in 70 hours it average speed upstream is 210703 miles per hour. On our trip we burned 35 gallons of fuel at an average speed of 22 knots and it took just over 2 hours to run 45 nautical miles. The speed of boat in still water is 12 miles per hour and speed of current is 9 miles per hour.
