# How much Distance Cover by Car?

A car complete a journey in 5 hours. It complete half the distance at 20 kmph and the rest at 30 kmph. The length of the journey is-

- 50 km.
- 100 km.
- 120 km.
- 240 km.

**Answer: (c) 120 km.
Explanation:-
**Let be the distance = X km

Time taken = 5 hrs

According to question, X/2 x 20 + X/2 x 30 = 5 (Time = distance/speed)

(3X + 2X) = 5 x 120

5X = 5 x 120

X = 120 km.

Hence, the length of the journey = 120 km.
