If a population of 50 Paramecium present in a pool increases to 150 after an hour, what would be the growth rate of population ?

Options

A. 150/ hour
B. 200 / hour
C. 5 / hour
D. 100 / hour

Explanation

To find the growth rate of the Paramecium population, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Initial and Final Population**:
- The initial population (at time \( t_1 \)) is given as 50 Paramecium.
- The final population (after 1 hour, at time \( t_2 \)) is given as 150 Paramecium.

2. **Use the Growth Rate Formula**:
- The growth rate can be calculated using the formula:
\[ \text{Growth Rate} = \text{Population at } t_2 - \text{Population at } t_1 \]

3. **Substitute the Values**:
- Substitute the values into the formula:
\[ \text{Growth Rate} = 150 - 50 \]

4. **Calculate the Growth Rate**:
- Perform the subtraction:
\[ \text{Growth Rate} = 100 \text{ Paramecium per hour} \]

5. **Conclusion**:
- The growth rate of the Paramecium population is 100 Paramecium per hour.
