Speed, Distance And Time Problems
Akopọ
Speed ties together two everyday quantities, distance and time, in a single tidy relationship. Once you know any two of speed, distance and time, the third follows at once. This one idea answers a huge range of real questions, from how long a journey takes to how fast you must travel to arrive on time.
In this lesson you will use the relationship between speed, distance and time to solve problems involving average speed. You will learn to rearrange the formula confidently and, just as importantly, to keep your units consistent so the answers come out right.
