| The speed of a stream is 3 km/h and the speed of a man in still water is 5 km/h. The time taken by the man to swim 26 km downstream is [SSC (10+2) 2012] |
A) \[5\frac{1}{2}h\]
B) \[8\frac{2}{3}h\]
C) \[3\frac{1}{4}h\]
D) \[13\,\,h\]
Correct Answer: C
Solution :
| Speed of stream \[=3\,\,km/h\] |
| Speed of man in still water \[=5\,\,km/h\] |
| Now, speed of man downstream \[=(3+5)=8\,\,km/h\] |
| \[\therefore \]Time taken to travel 26 km downstream |
| \[=\frac{26}{8}=\frac{13}{4}=3\frac{1}{4}h\] |
