Rahul swims in a 60 m long pool. He covers 120 m in one minute by swimming from one end to the other and back along the same straight path. What is the average speed of Rahul in m `s^(-1)` ?

Explanation

To find the average speed of Rahul while swimming in the pool, we can follow these steps:

### Step 1: Understand the total distance covered
Rahul swims from one end of the pool to the other and then back. The length of the pool is 60 meters. Therefore, the total distance he swims is:
- Distance to one end = 60 m
- Distance back = 60 m
- Total distance = 60 m + 60 m = 120 m

### Step 2: Determine the total time taken
Rahul takes 1 minute to cover this distance. We need to convert this time into seconds since we want the average speed in meters per second (m/s).
- 1 minute = 60 seconds

### Step 3: Calculate the average speed
Average speed is calculated using the formula:
\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]
Substituting the values we have:
\[ \text{Average Speed} = \frac{120 \text{ m}}{60 \text{ s}} = 2 \text{ m/s} \]

### Final Answer
The average speed of Rahul is **2 m/s**.
