One minute of one degree on a great circle is a mile, so there are 60 miles in a degree.
And here is a different definition from the sailor's travel definition ....
A degree of latitude is the same all over the earth. It is 1/360 of
the circumference of the earth, and you can look up the radius of the
earth at this Web site, then multiply by 2pi:

Degrees of longitude are the same size as latitude at the equator, but
they get smaller and smaller as you go toward the pole. At the pole,
the size of a degree of longitude becomes zero.
The relation between latitude and the size of a degree of longitude is
called a "cosine" function, from trigonometry. The latitude of
Oklahoma is about 34 degrees north, and the cosine of that angle is
0.83. This means that adegree of longitude in Oklahoma is about 0.83
times as great as a degree of latitude.

I will assume you are talking about latitude and longitude degrees?
That depends on how close to the poles you are. The closer to the equator, the farther apart the degrees. The closer to the poles, the closer the degrees.

Radius of Earth is 6 378.1 KM
1 Degree is 177.17 KM ie 110.08 miles
That is on the Equator

The question is meaningless, unless you specify the distance between the three points of a triangle. In other words, two triangles can be identical in shape but very different in size.

If your are talking about temperature, then to reach one degree, a plane can travel more than 10miles with the same timing. But if you are talking about nautical mile in the map of our earth, then your have to check the atlas for it........
