Relative humidity is calculated using the formula:
\[
\text{Relative Humidity} = \left( \frac{\text{Actual Vapor Pressure}}{\text{Saturation Vapor Pressure}} \right) \times 100\%
\]
In this case, the actual vapor pressure is 30 mb and the saturation vapor pressure is 40 mb. Plugging in these values:
\[
\text{Relative Humidity} = \left( \frac{30 \text{ mb}}{40 \text{ mb}} \right) \times 100\% = 0.75 \times 100\% = 75\%
\]
Therefore, the approximate relative humidity is **75%**.
