A) 32 min
B) 24 min
C) 16 min
D) 8 min
Correct Answer: A
Solution :
Time taken by launch from \[A\text{ }\to \text{ }B\text{ }\to \text{ }C\] is equal to time taken by float from A to C: ----------------------- \[\to u=3\,\,m/s\] \[\frac{4800}{8-3}\,\,+\,\,\frac{4800+x}{8+3}\,\,=\,\frac{x}{3}\] Solve to get time taken: \[t=\frac{x}{3}\,\,=\,\,32\,\,\min \]You need to login to perform this action.
