Explain why the total phase of a solar eclipse lasts several minutes, and a total lunar eclipse is about an hour.

The size of the lunar shadow on Earth is about 300 km, so a total solar eclipse lasts up to 7 minutes. The diameter of the Earth is 4 times the diameter of the Moon, so the Moon is completely immersed in the Earth’s shadow and the total phase of the lunar eclipse lasts about an hour.
