"Given:

Distance to travel: 50 km.

Hours to travel: 3.25 or 3 ¹/₄  or  13/4 hours

Average Speed: R = ?

Formula:

Distance = Time × Rate

Derive the equation to solve for R:

D = R × T

RT/T = D/T

R = D/T

Substitute the given values:

R = 50 km / 3.25 hour

R = 50 km/(13/4) hours

(When dividing fraction, multiple the dividend by the reciprocal of its divisor):

R = 50 km × 4/13  hours  

R = 200 km/13 hours   or  15.4 km/h
