A) \[\frac{5}{3}\]min / 2 min
B) 1 min / 2 min
C) 2 min / 3 min
D) \[\frac{4}{3}\] min / 3 min
Correct Answer: A
Solution :
As speed \[=\frac{1000}{5}=200\,m\]/minute B's speed \[=\frac{1000}{8}=125\,m\]/minute C's speed \[=\frac{1000}{10}=100\,m\]/minute Distance covered by C in 2 minutes=200 metre Distance covered by B In 1 minute=125 metre Relative speed of A with respect to C=d00 metre \[\therefore \] Time \[=\frac{200}{100}=2\] minutes Relative speed of A with respect of B=75 metre \[\therefore \] Time \[=\frac{125}{75}=\frac{5}{3}\] minutesYou need to login to perform this action.
