A) \[9\frac{1}{4}h\]
B) \[9\frac{3}{4}h\]
C) \[9\frac{2}{3}h\]
D) \[9\frac{1}{3}h\]
Correct Answer: B
Solution :
Distance walked by 2nd man \[=\frac{2\times 12\times 19}{4\times 4}\,\text{km}\] \[=\frac{13\times 19}{8}\,\text{km}\] \[\therefore \] Time taken by 2nd man \[=\frac{\frac{13\times 19}{8}}{\frac{19}{6}}=\frac{39}{4}=9\frac{3}{4}h\]You need to login to perform this action.
