A) \[2\frac{2}{3}h\]
B) \[3\frac{1}{3}h\]
C) \[2\frac{1}{3}h\]
D) None of these
Correct Answer: B
Solution :
Let length of circular track = x km Let A, B meet after t h. Then, (distance covered by A in t h) + (distance covered by b in t h) = x \[\therefore \] \[\frac{x}{\frac{15}{2}}t+\frac{x}{6}t=x\] \[\therefore \] \[t\left( \frac{2}{15}+\frac{1}{6} \right)=1\] \[\therefore \] \[t=\frac{30}{9}=\frac{10}{3}=3\frac{1}{3}\]You need to login to perform this action.
