If a person walks at 15 km/h instead of 11 km/h, he would have walked 22 km more. The actual distance travelled by him is:A)50kmB)60.5kmC)40.5kmD)55km

To solve this problem, we can use the concept of relative speed.

The difference in speed is 15 km/h - 11 km/h = 4 km/h.

This means that the person walks 4 km more per hour when walking at 15 km/h than when walking at 11 km/h.

Given that the person would have walked 22 km more at the faster speed, we can find out the time he spent walking by dividing the extra distance by the difference in speed.

So, the time = 22 km / 4 km/h = 5.5 hours.

Now, we can find the actual distance travelled by the person by multiplying the time spent walking by his slower speed.

So, the actual distance = 5.5 hours * 11 km/h = 60.5 km.

Therefore, the answer is B) 60.5 km.
