How is solving for speed similar to solving for time?

Question

They both require that two numbers be added.
They both require that two numbers be subtracted.
They both involve writing a rate.
They both use the same units of measure.

Answer 1

Solving for speed and solving for time are similar in that they both involve writing a rate.

In the context of the equation for speed, the formula is:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

When you are rearranging this equation to solve for time, you would use:

\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

In both cases, you are working with the concepts of distance, speed (or rate), and time, thus involving the same units of measure (e.g., meters, kilometers, miles for distance, and hours or seconds for time).

Thus, the correct answer is: They both involve writing a rate.
