nmodi Jul 17th, 2005 Ans. 384 Kms. Speed of boat = 10 Kmph; Let speed of river = x; Relative speed of boat in upstream = 10 - x; Relative speed of boat in downstream = 10 + x; Since, Distance = Velocity * Time; Distance upstream = (10 - x) * 24; Distance downstream = (10 + x) * 16; Distance upstream = Distance downstream; (10 - x) * 24 = (10 + x) * 16; therefore x = 2; Total distance = distance upstream + distance downstream; Total distance = (10 - x) * 24 + (10 + x) * 16; Total distance = 8 * 24 + 12 * 16 = 192 + 192 =384 Km

nimmi Jul 27th, 2005 speed in still water=0.5(speed upstream+speed downstream) let distance be x kms. 0.5((x/24)+(x/16))=10 solving,distance x=192.

jaspreet(jagz) Feb 19th, 2006 D=16(10+x) =24(10-x) // D is the distance traveeled.. and x is the speed of the stream).......=>x=2 kmphthus D=192 km

vishwa828 Profile Answers by vishwa828 Dec 7th, 2006 hey the answer shoud be 192+192=384 since he asked for the distance covered....

## Speed of boat in still water 10 kmph.If the boat takes 24hr in up stream and 16hr in down stream to cross the same distance, then what will be the distance covered.
