A car is fitted with a convex side-view mirror of focal length 20 cm. A second car 2.8m behind the first car is overtaking the first car at a relative speed of 15 `m/s`. The speed of the image of the second car as seen in the mrror of the first one is:

`(1)/( 15 ) m//s`

` 10 m//s`

`15 m//s`

` (1)/(10) m//s`
