Time, Distance, Pace, Speed formulas and relationships
time = speed × distance
time = pace time per unit distance × distance
distance = time / speed
distance = time / pace time per unit distance
speed = time / distance
pace time per unit distance = time / distance
speed = distance / time
speed distance per unit time = distance / time
