Answers to these questionsinvolve experiments and variables. 95 km/h is the same speed as 59 mph, which is slower than 75 mph. An equation (also called a formula) shows you how to get speed, distance, or time if two of the three values are known.Calculating Let the letter d stand for distance traveled and the letter t stand for speed time taken. The letter v is used to represent speed because it refers to the word velocity (later we will learn that velocity is speed plus direction).
