Question 106

If a person would have walked at 12 km/h instead of 10 km/h, he would have walked 20 km more. The actual distance travelled by him when he walked at the pace of 10 km/h is

Solution

Assume that the person traveled for 't' hours. 

As per the question (extra distance because of increased speed), 12t-10t = 20, which implies that t = 10 hours. 

Hence, the distance traveled by the person in 10 hours at the speed of 10 kmph shall be 100 km.
