The question is incomplete. Assuming it asks for the time at the Prime Meridian ( $0^\circ$ longitude):

Identify the given time and longitude.
The time in Kinshasa ( $20^\circ$ W) is 9:00 am.
Determine the longitude difference.
The Prime Meridian is at $0^\circ$ longitude.
The difference in longitude between Kinshasa ( $20^\circ$ W) and the Prime Meridian ( $0^\circ$ ) is:
$\text{Longitude difference} = 0^\circ - (-20^\circ) = 20^\circ$
Convert the longitude difference to time difference.
We know that $15^\circ$ of longitude corresponds to 1 hour of time difference.
$\text{Time difference} = \frac{20^\circ}{15^\circ/\text{hour}} = \frac{4}{3} \text{ hours}$
To convert this to hours and minutes:
$\frac{4}{3} \text{ hours} = 1 \text{ hour and } \left(\frac{1}{3} \times 60\right) \text{ minutes} = 1 \text{ hour and } 20 \text{ minutes}$
Calculate the time at the Prime Meridian.
Since the Prime Meridian ( $0^\circ$ ) is to the east of Kinshasa ( $20^\circ$ W), the time at the Prime Meridian will be later than in Kinshasa.
$\text{Time at Prime Meridian} = \text{Time in Kinshasa} + \text{Time difference}$ $\text{Time at Prime Meridian} = 9:00 \text{ am} + 1 \text{ hour } 20 \text{ minutes}$ $\text{Time at Prime Meridian} = 10:20 \text{ am}$
The time at the Prime Meridian ( $0^\circ$ longitude) is $\boxed{\text{10:20 am}}$ .
