Final answer:
The form of the speed equation in each scenario can be written as: Time = Distance / Speed, Speed = Distance / Time, and Distance = Speed * Time.
Step-by-step explanation:
The form of the speed equation in each scenario can be written as:
a. Time = Distance / Speed, where you know the distance and speed and want to find the time.
b. Speed = Distance / Time, where you know the time and distance and want to find the speed.
c. Distance = Speed * Time, where you know the speed and time and want to find the distance.
