To determine the remaining distance Rachel has to drive, we can look at the equation provided:
D = -38t + 220
In this equation, D represents Rachel's remaining distance in meters, and t represents the time in seconds.
To find the remaining distance, we need to substitute the value of t into the equation. However, since we don't have a specific value for t, we cannot determine the exact remaining distance without more information.
If you have a specific value for t, you can substitute it into the equation to find the corresponding remaining distance for that specific time.
