# Speed Distance Time Calculator

## Calculator Use

Calulate speed, distance or time from the formula **d = st** which means distance equals speed times time or

You may use the equivalent formula **d = rt** which means distance equals rate times time or

Rate and speed are the same, a distance per unit time such as miles per hour or kilometers per hour. r = s = d/t

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time or

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed or

For speed, displacement and velocity calculations in physics use the Displacement Calculator.
