Question

The planet venus is on average 2.5x10^7 kilometers from earth. The planet mars is on average 2.25x10^8 kilometers from earth. What is the average distance from venus to mars?

Answer 1

The average distance from venus to mars is 2.5x10⁸ kilometers.

Explanation:

We know:

d₁: average distance between venus and earth = 2.5x10⁷ km

d₂: average distance between mars and earth = 2.25x10⁸ km

We can find the average distance from venus to mars as follows:

`d_(t) = d_(1) + d_(2)`

First, we need to equal the base power 10 so we can sum both distances:

`2.25 \cdot 10^(8) = 2.25 \cdot 10^(7) * 10 = 22.5 \cdot 10^(7) km`

Now, average distance:

`d_(t) = 2.5 \cdot 10^(7) + 22.5 \cdot 10^(7) = (2.5 + 22.5) \cdot 10^(7) = 25 \cdot 10^(7) km = 2.5 \cdot 10^(8) km`

Therefore, the average distance from venus to mars is 2.5x10⁸ kilometers.

I hope it helps you!
