Here's why:

* The Equator is an imaginary line that circles the Earth at 0 degrees latitude. It divides the Earth into the Northern and Southern Hemispheres.

* The Tropic of Cancer is another imaginary line that circles the Earth at approximately 23.5 degrees north latitude. It marks the northernmost point on Earth where the sun can be directly overhead at noon.

Since they are at different latitudes, the equator and Tropic of Cancer cannot meet.
