If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more.

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/Solution

50 km

Steps/Work

Let the actual distance travelled be x km.
Then, x/10 = (x + 20)/14
=14x = 10x + 200
4x = 200
x = 50 km.

Calculated Answer

50

Step by Step Solution

In order to solve problem, you must evaluate n₁ * n₂ / (n₀ - n₁).

n₀ =	14
n₁ =	10
n₂ =	20

n₁ * n₂ / (n₀ - n₁)
Evaluate n₀ - n₁ = 4
n₁ * n₂ / 4
Evaluate n₂ / 4 = 5
n₁ * 5
Evaluate n₁ * 5 = 50
50
The answer to the problem and the result of n₁ * n₂ / (n₀ - n₁) is 50
