Also it covers 40 km upstream and 48 km downstream in 9 hours.

A boat goes 32 km upstream. Let the speed of boat in still water be x kmhr let the speed of stream be y kmhr Now Speed downstream x y Speed upstream x y Given that A boat goes 30 km upstream and 44 km downstream in 10 hours Time taken to go 30 km upstream Time taken to go 44 km downstream 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝑜𝑓 30 𝑘𝑚𝑆𝑝𝑒𝑒𝑑 𝑢𝑝𝑠𝑡𝑟𝑒𝑎𝑚 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝑜𝑓 44 𝑘𝑚𝑆𝑝𝑒𝑒𝑑. Also time taken for us is 13 more than for ds. Also it travels 40 km upstream and 84 km downstream in 12 hrs.

32 km-- View Answer. A boat goes 12 km downstream and comes back to the starting point in 3 hours. A boat travels 24 km upstream in 6 hours and 20 km down stream in 4 hours.

It can go 16 km upstream and 32 km downstream in the same time. Let spead of the boat be X kmh that of stream be Ykmh 32X-Y36XY7 Or 32X32Y36X-36Y7 Or 68X-4Y7X2-Y2-1 Similarly 88X-8Y 9X2-Y2. Aptitude Questions Boats and Streams.

A motor boat goes 10 km upstream and back again to the starting point in 55 minutes. A motor boat whose speed is 24 kmhr in still water takes 1 hr more to go 32 km upstream than to return downstream to same spot. If the speed downstream is a kmhr and the speed upstream is b kmhr then.

Find the speed of boat in still water and that of stream. A motor boat whose speed is 24 kmhr in still water takes 1 hr more to go 32 km upstream than to return downstream to same spot. Finf the spead of the boat in still water and that of the stream.

Find the speed of the boat in still water and rate of the current. In 13 hours it can go 40 km upstream and 55 km downstream. A boat goes 30 km upstream and 44 km downstream in 10 hours.
