    Let the distance traveled by the car be x KMs
    Distance traveled by the bike = 168 KMs
    Speed of car is double the speed of bike
    => $$frac{x}{3:40 - 2:00}$$ = $$2 imes frac{168}{3:40 - 1:00}$$
    => $$frac{x}{100}$$ = $$2 imes frac{168}{160}$$
    => x = 210
    Hence the distance between A and B is x + 168 = 378 KMs
