Final answer:
The bus traveled a distance of 510 miles.
Step-by-step explanation:
To calculate the distance traveled, we can use the formula D = s * t, where D represents distance, s represents speed, and t represents time. In this case, the bus traveled at a speed of 60 mi/h for 8.5 hours. Plugging these values into the formula, we have D = 60 mi/h * 8.5 h = 510 miles. Therefore, the bus traveled a distance of 510 miles.
