Murthy drove from town A to town B. In the fist hour, he travelled $$\frac{1}{4}$$ of the journey. In the next one hour, he travelled $$\frac{1}{2}$$ of the journey. In the last 30 minutes, he travelled 80 km. Find the distance of the whole journey.
Let the total journey be x km.
Remaining distance of the journey = 80 km
x - $$\frac{x}{4} -Â \frac{x}{2}$$ = 80 km
$$\frac{x}{4} = 80$$
x = 320 km
$$\therefore$$ Total distance is 320 km of whole journey.
