Question

What is the distance formula?

Answer 1

The question is a little vague but I am assuming you mean distance in relation to speed and time.  

For that, the equation is :

Distance = Speed x time

Answer 2

Distance=Rate*Time

Answer 3

Which distance formula are you referring to?

Distance=Rate x Time?

Or

d=√(x2-x1)squared+(y2-y1)

(radical sign is over all of that)

Answer 4

In Geographical terms, the distance between 2 points P & Q whose latitudes (phiA, phiB), longitudes (lambdaA, lambdaB) & D is difference of their longitudes (longitudinal distance < 180 degrees) are given, the radial distance along the great circle is given as

cosR = sin phiA * sin phiB + cos phiA * cos phiB * cos D.

If the spots A & B are in not in the same (N or S) hemisphere, one of them shall be considered as negative. The former in the sum will be negative then.

R (degrees) is multiplied with 60 to get nautical miles, or multiplied with 69 to get st. miles, or multiplied with111 to get km.
