Question

a boat covers a certain distance upstream in 3¹/² hours , while it comes back in 3 hours . if the speed of the stream be 2 km per hours , what is the seeds of the boat in still water​

Answer 1

Step-by-step explanation:

Let the speed of boat be x.

Upstream=x-2

downstream=x+2.

7x-14/2=3x+6.

7x-14=6x+12

7x-6x=12+14

x=26.

Speed of boat is 26km/hr.
