Final answer:
The equation to calculate the distance Taylor drives after t hours at a constant speed of 55 mph is d = 55t.
Step-by-step explanation:
The equation to find the distance d after traveling t hours at a constant speed is given by the formula d = rt, where r is the rate of speed and t is the time in hours. In Taylor's case, she is driving at 55 miles per hour, so the equation becomes d = 55t. This simple distance formula is a key concept in algebra and physics, illustrating the linear relationship between distance traveled and time at a constant speed.
