Question

the speed of a motor boat going downstream is 50.4 km per hour and going upstream is 20 3.3 km per hour find the speed of the boat in the still water and speed of the current​

Answer 1

let the speed of current be S

let the speed of water be s

upstream S +s =203.3

downstream S - s =50.5

add 2S =253.8

S =126.9

s =203.3 - S

=203.3 - 126.9

=76.4
