I. The speed of boat is 16 kmph in still water. |
II. The distance (in km) is half the numerical value of the speed of the boat. |
III. The speed of the stream (in kmph) is \[\frac{1}{4}\] the numerical value of the distance. |
A) Any two
B) I or II or III
C) Either I and II or III
D) All I, II, III
E) Both II and III
Correct Answer: D
Solution :
From I, II and III. Speed of boat in still water = 16 kmph Distance covered \[=\frac{1}{2}\times 16=8\,km\] Speed of stream = 2 kmph Speed of boat against the stream = 16 - 2 = 14 kmph \[\therefore \] Time taken\[=\frac{8}{14}hr\]You need to login to perform this action.
