A) \[\text{3 km}/\text{h}\]
B) \[\text{4 km}/\text{h}\]
C) \[\text{5 km}/\text{h}\]
D) \[\text{6 km}/\text{h}\]
Correct Answer: B
Solution :
On putting the value of x in eq. (2), we get |
\[10+y=14\] |
\[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,y=14-10=4\] |
\[\therefore \] Speed of the stream is 4 km/h. |
