1.	Radha takes 4 h to travel from her village to her friends's city by bus. If she goes by car, whose speed is (2)/(3) times that of the bus, then how much time will she take to cover the same distance?
Answer» 3 h 8 h 12 h 6 h Solution :Let the speed of bus be s kmph. The speed of the car `= (2)/(3)` s kmph Let the distance between the village and the city be d km. `"Speed" XX "Time" = "Distance covered"` For bus, `d = s xx 4 ""(1)` For car, `d= (2s)/(3) xx t "" (2)` `RARR " From Eqs (1) and (2),"` ` s xx 4 = (2s)/(3) xx t` t = 6 h. Hence, the correct option is (d).
