A motorboat has two throttle positions on its engines.the high speed position propels the boat at 30km/hr in still water and the low speed position gives one third the higher speed. the boat moves from its dock downstream on a river with throttle at low speed position . the return trip took 5% longer time that it did for the downstream trip.Determine the velocity of the flow of the river.

and the net upstream speed will be equal to
.
and the time taken while going upstream would be equal to:
