If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:

Answer: Option

Explanation:

Let the actual distance travelled be *x* km.

Then, | x |
= | x + 20 |

10 | 14 |

14*x* = 10*x* + 200

4*x* = 200

*x* = 50 km.

For the same interval if the person travelled in 14 kmph so only.

or else you could solve like this

1st hour 10 =14

2nd hour 20 =28

3rd hour 30 =42

4th hour 40 =56

5th hour 50 =70

At speed 10 kmph he reaches 50 km at the same time if he travels in 14 kmph he would reach 70 km. So 70 - 50 = 20. I think u got it.

I'm not clear with the answer. Why did you take the time same in both the cases?
