33. The speed of a boat in still water is 76 km/hr. If the speed of the boat against the stream is 36 km/hr, what is the speed of the stream?
39 km/hr
0 41 km/hr
45 km/hr
40 km/hr​

Answer 1

Answer:

speed of the stream will be 40kmph

Step-by-step explanation:

speed of boat in still water - speed of boat against the stream

76-36=40kmph

Answer 2

Speed of stream is 40 km/h so the correct option is (d) 40 km/h.

The speed of a boat in still water is 76 km/h. If the speed of the boat against the stream is 36 km/h.

We have to find the speed of stream.

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

Here given,

Speed of boat in still water = x = 76 km/h

Speed of boat against the stream = (x - y) = 36 km/h [we say it, “upstream” ]

⇒ 76 - y = 36

⇒y = 40 km/h

Therefore the speed of stream is 40 km/h.
