Question

if downstream and upstream speed is 24 and 12 then what is speed of motor and speed of stream​

Answer 1

Step-by-step explanation:

Let the speed of the stream be x km/hrSpeed of the boat in still water =24 km/hr

Speed of the boat in upstream =(24−x) km/hr

Speed of the boat in downstream =(24+x) km/hr

Distance between the places is 32 km.

Time to travel in upstream = 24–xd hrTime to travel in downstream = 24+xx hr

Time of upstream journey = Time of downstream journey +1 hr

Therefore,

=24+x)768+32x−768+32x=164x=576–x 2x 2+64x−576=0

On factoring, we get(x+72)(x−8)=0

So,

x=−72 or 8 (speed of the stream cannot be negative)Therefore, speed of stream is 8 km/hr.

Hope this will help you buddy...
