Let:
- 𝑥 = distance traveled in miles
- 𝑦 = time in hours
The equation relating the distance to the time is:
𝑥 = 𝑦 * 𝑟
where 𝑟 represents the constant rate of the car in miles per hour.
Your family decides to take a long road trip for the summer. You will be riding in the
car while it moves at a fairly constant rate for eight hours to reach your destination.
Write an equation using the variables 𝑥𝑥 and 𝑦𝑦 that relates the distance to the time.
Label the variables to show what they stand for in the equation. Be careful of which
variable you use for the independent and dependent quantities.
