How can one calculate the speed of rotation of a point on the Earth's surface about the Earth's axis, given only a latitude?

While the simplest approach might be to assume the Earth is a sphere and it rotates once per day, it's rotation isn't exactly 24 hours, and the Earth is definitely not exactly a sphere!

Launches often happen near the equator in order to take advantage of Earth's rotation speed. This is why more launches are towards the East than towards the West.

What is the speed at the surface of the Earth's in KPH as it rotates in 24 hours at Latitude 14.6042? Or if I stay in Manila, Philippines, and it takes 24 hours for the earth to make a complete rotation on its axis, how fast was I travelling to complete that rotation?
