You may see these equations simplified as sdt where s is speed d is distance and t is time. A boy walks at a speed of 4 kmph. You can use the equivalent formula d rt which means distance equals rate times time.
Formula for time fracdistancetime Or it can be written as fracds Distance.
To solve for time use the formula for time t ds which means time equals distance divided by speed. Which implies Speed Distance Time and. It is abbreviated as. Set up the formula for speed.
