The time in Kinshasa 20°W is 9.00 am. What is the time in your locality given that your locality is at 30°E?

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

Step 1: Identify the given time and longitude. The time in Kinshasa ($20^\circ$W) is 9:00 am.

Step 2: 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: $Longitude difference = 0^\circ - (-20^\circ) = 20^\circ$

Step 3: Convert the longitude difference to time difference. We know that $15^\circ$ of longitude corresponds to 1 hour of time difference. $Time difference = \frac{20^\circ}{15^\circ/hour} = \frac{4}{3} hours$ To convert this to hours and minutes: $\frac{4}{3} hours = 1 hour and \left(\frac{1}{3} \times 60\right) minutes = 1 hour and 20 minutes$

Step 4: 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. $Time at Prime Meridian = Time in Kinshasa + Time difference$ $Time at Prime Meridian = 9:00 am + 1 hour 20 minutes$ $Time at Prime Meridian = 10:20 am$

The time at the Prime Meridian ($0^\circ$ longitude) is $\boxed{10:20 am}$.
