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` shown in figure . the ratio of distance travelled by A ,B and C by the instant they meet for the first time is

Options

A. `3:2`
B. `5:4`
C. `3:5`
D. data insufficient

Answer

B

Explanation

`(d_(B))/(d_(c))=(v_(B)t)/(v_(C)t)=(2.5)/(2)=(5)/(4)`
