The mean semi-major axis has a value of 384,402 km (238,856 mi). The time-averaged distance between Earth and Moon centers is 385,000.6 km (239,228.3 mi). The actual distance varies over the course of the orbit of the Moon, from 356,500 km (221,500 mi) at the perigee to 406,700 km (252,700 mi) at apogee, resulting in a differential range of 50,200 km (31,200 mi).

Answer this question based on the passage: what is the distance from the earth to the moon? Okie... think carefully first, then make a decision:
The important part for answering this question is: The actual distance varies over the course of the orbit of the Moon, from 356,500 km (221,500 mi) at the perigee to 406,700 km (252,700 mi) at apogee, resulting in a differential range of 50,200 km (31,200 mi). So, the answer is 356,500 km ( 221,500 mi ) at the perigee to 406,700 km ( 252,700 mi ) at apogee.
