km to reach the school. How far did she walk ?​

Answer 1

Answer:

Here is ur answer

Step-by-step explanation:

Lets assume the distance from Ram’s house to the school be X.

When Ram travels at 5 kmph he takes X/5 hours to reach his school.

When Ram travels at 4 kmph he takes X/4 hours to reach his school.

We know that the difference between the time taken with the first case (5 kmph) and the second case (4 kmph) is 10 minutes (5 minutes early v/s 5 minutes late).

10 minutes is 1/6 th of an hour.

Therefore, X/4 - X/5 = 1/6.

This can be rewritten as :

X/20 = 1/6 or X = 20/6 = 3.33 km.

Therefore the distance from Ram’s house to his school is 10/3 or 3.33 km.
