Here's how to figure out the difference in longitude between Beijing and Pikes Peak:

* Find the longitudes:

* Beijing, China: 116.4074° E

* Pikes Peak, Colorado, USA: 105.0884° W

* Account for the difference in East and West:

* Since longitudes are measured from the prime meridian (0°), East longitudes are positive, and West longitudes are negative. To find the total difference, we need to add the absolute values of both longitudes.

* 116.4074° + 105.0884° = 221.4958°

Therefore, the difference in longitude between Beijing and Pikes Peak is approximately 221.4958 degrees.
