Question

a boat goes 30 km upstream and 44 km downstream in 10 hours . In 13 hours it can 40 km upstream and 234 km down stream . determine the speed of the stream and that of the boat in still water​

Answer 1

Answer:

Let speed of boat in still water be x km/h and speed of stream be y km/h.

Speed upstream= (x - y) km/h

Speed downstream= (x + y) km/h

On subtracting, we get,

On solving, we get,

Speed of boat in still water = 8 km/h

And, Speed of stream = 3 km/h

Step-by-step explanation:

Answer 2

Hii mate,

INFORMATION GIVEN IN QUESTION IS WRONG BECAUSE SPEED CANNOT BE NEGATIVE.

HOPE IT HELPS,

PLEASE THANK AND MARK AS BRAINLIEST.
