Step 1 . Given

The given rate is $\frac{390 m}{1 min}$ .

Step 2 . To determine

We have to determine the equivalent rate in meter per hour.

Step 3 . Calculation

In order to find an equivalent rate, we will convert from meters per minute to meters per hour.

For that, we multiply the rate by a conversion factor.

We know that 60 minutes = 1 hour, it means. $\frac{60 min}{1 hr} = 1$

$\begin{array}{l} \frac{390 m}{1 min} \\ \Rightarrow \frac{390 m}{1 min} \times \frac{60 min}{1 hr} [Multiply rate by common conversion factor] \\ \Rightarrow \frac{390 m}{1 min} \times \frac{60 min}{1 hr} [Divide out common factor and unit] \\ \Rightarrow \frac{23400 m}{1 hr} [Simplify] \end{array}$

So, the equivalent rate of $\frac{390 m}{1 min}$ is 23400 meters per hour.
