Final answer:
To calculate 7 times as long as 3,098 kilometers, we would perform the multiplication 3,098 km x 7, which gives us 21,686 km. This mathematical calculation helps us understand scaling and the vastness of astronomical distances.
Step-by-step explanation:
The student has asked for the calculation that is 7 times as long as 3,098 kilometers. To find this distance, we multiply 3,098 km by 7. The resulting answer provides us with the distance that is seven times longer than the initial value.
Multiply the given length (3,098 km) by 7.
The calculation will be 3,098 km x 7 = 21,686 km.
This is the distance that is 7 times as long as 3,098 kilometers.
Such comparisons help us understand vast distances, such as those found in the scale of the universe. Just for an example, the light-year distance mentioned, which is almost 10,000,000,000,000 km, provides us with a sense of how massive the scales are when we talk about astronomical measurements. The Earth's diameter, the distance to the Sun (1 AU), and the distance to other stars like Alpha Centauri further put into perspective the vastness of space relative to distances on Earth.
