Back to paper

If Ramesh walks at a speed of 15 km/h, instead of 12 km/h, he would have walked 2 km more in the same time. What is the actual distance (in km) travelled by Ramesh at 12 km/h in the same time?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 8

Concept Used:

Speed = Distance/time

Explanation:

According to the given question,

Let the distance travelled be x km in t hours.

Distance travelled by Ramesh at 12 kmph = 12t

⇒ x = 12t

Distance travelled by Ramesh at 15 kmph = (x + 2)/t

⇒ 15t = x + 2

⇒ 15t = 12t + 2

⇒ 3t = 2

⇒ t = 2/3

Now, the actual distance travelled by Ramesh = 12t = 12×2312 \times {2 \over 3} = 8 km

Hence the required answer is 8 km.
