Understanding the Basics of Light Speed

Light travels at an incredible speed of approximately $3.0 \times 10^8$ meters per second. This speed is a fundamental constant in physics and is denoted by the letter $c$. It is a crucial parameter in various fields, including astronomy, optics, and telecommunications.

Calculating Distance Using Light Speed

To calculate the distance light travels in a given time, we can use the formula:

$$\text{Distance} = \text{Speed} \times \text{Time}$$

In this case, we are given the speed of light ($3.0 \times 10^8$ meters/second) and the time (4,500 seconds). We can plug these values into the formula to find the distance light travels in 4,500 seconds.

Using a Calculator to Find the Distance

If we use a calculator to find the distance, we would get:

$$\text{Distance} = 3.0 \times 10^8 \times 4,500$$

Using a calculator, we can evaluate this expression to find the distance.

Evaluating the Expression

To evaluate the expression, we can follow the order of operations (PEMDAS):

1. Multiply $3.0 \times 10^8$ by $4,500$:

$$3.0 \times 10^8 \times 4,500 = 1.35 \times 10^{12}$$

Therefore, the distance light travels in 4,500 seconds is $1.35 \times 10^{12}$ meters.

Conclusion

In conclusion, we have calculated the distance light travels in 4,500 seconds using the formula $\text{Distance} = \text{Speed} \times \text{Time}$. We have also used a calculator to evaluate the expression and found that the distance is $1.35 \times 10^{12}$ meters.
