Three particles `A,B` and `C` move in a circle in anticlockwise direction with speeds `1min^(-1),2.5ms^(-1)` and `2ms^(-1)` respectively. The initial positions of `A`,`B` and `C` are shown in fig. The ratio of distance travelled by `B` and `C` by the instant `A,B` and `C` meet for the first time is

Options

A. `3:2`
B. `5:4`
C. `3:5`
D. `3:7`

Answer

B

Explanation

The ratio of distance travelled by `B` and`C` in same duration of time `t` is `=v_(B):v_(C)=5:4`
