Final answer:
The question has a possible error in the distance calculation. Assuming the distance was meant to be positive, we would normally divide it by the time to find the speed. Clarification from the student is needed.
Step-by-step explanation:
The question is asking us to determine the speed of a vehicle given it travels a distance of 54 - 107 - 6 miles in t + 2 minutes. To find speed, we use the formula speed = distance/time. Therefore, we first perform the arithmetic in the distance given, which is 54 - 107 - 6 to get a negative number, which isn't realistic for a distance, indicating a possible typo or error in the question. Assuming the intended distance was positive, we would plug it into the speed equation along with the time, but since it's not clear, we cannot provide a definite answer. We should clarify the distance with the student first.
