A new unit of length is chosen such that the speed of light in vecuum is unity. What is the distance between the sun and the earth in terms of the new unit, if light takes 8 min and 20 sec. to cover the distance ?

Explanation

To solve the problem, we need to determine the distance between the Sun and the Earth in a new unit of length where the speed of light in vacuum is defined as unity (1 unit per second). Given that light takes 8 minutes and 20 seconds to travel this distance, we can follow these steps:

### Step-by-Step Solution:

1. **Convert Time to Seconds:**
- First, we need to convert the time taken by light from minutes and seconds into total seconds.
- The time given is 8 minutes and 20 seconds.
- We know that 1 minute = 60 seconds.
