Question

A boat takes 5 hours to travel 12 km downstream and 16 km upstream, and it takes 7 hours to travel 16 km downstream and 24 km upstream. Find the speed of the boat in still water and the speed of the stream.​

Answer 1

Answer:

Step-by-step explanation:

speed downstream =speed of stiil water+speed of stream

12+16/5+7

28/12

2.3km/hr

speed upstream =speed of still water - speed of stream

=16+24/5+7

=40/12

=3.3km/hr

solving eq 1 and 2 we get ans
