They spent about two and a quarter hours together outside the spacecraft
Correction

Apollo 11’s moonwalk lasted more than 2.5 hours in total, but Armstrong and Aldrin were not together outside for 2.25 hours.

Full reasoning

NASA’s Apollo 11 mission overview says Armstrong stepped onto the Moon first, and Aldrin followed about 20 minutes later. NASA also says Aldrin spent one hour and 33 minutes on the surface, then re-entered the lunar module, and Armstrong followed 41 minutes later. So while the full EVA lasted more than two-and-a-half hours, the two astronauts were not together outside the spacecraft for “about two and a quarter hours.” Their overlap outside was much shorter.

In other words, the article appears to confuse the total moonwalk duration with the time both men were simultaneously outside.

    At about 109 hours, 42 minutes after launch, Armstrong stepped onto the moon. About 20 minutes later, Aldrin followed him... After Aldrin had spent one hour, 33 minutes on the surface, he re-entered the LM, followed 41 minutes later by Armstrong. The entire EVA phase lasted more than two-and-a-half hours.
