Question

a boat can travel upstream at 9 km hr and downstream at 12 kmph find the speed of boat in still water and speed of water
​

Answer 1

Solution :

Speed of boat upstream = 10 - 5 = 5 km/h

Speed of boat downstream = 10 + 5 = 15 km/h

∴ Total time taken =(Distance/Speed) =20/5+30/15=4+2=6h

speed of boat in still water and speed of water

speed of boat in still water and speed of water= 6h
