Four cars are moving along a straight road in the same direction. Velocity of car 1 is `10 m//s`. It was found that distance between car 1 and 2 is decreasing at a rate of `2 m//s`, whereas driver in car 4 observed that he was nearing car 2 at a speed of `8 m//s`. The gap between car 2 and 3 is decreasing at a rate of `3 m//s`.

(a) `t = 0`, after how much time t0 will the driver of car 2 see for the first time, that another car overtakes him?
(b) Which car will be first to overtake car 1?
