Final answer:
The bus traveled a distance of 225 km.
Step-by-step explanation:
To calculate the distance traveled, we can use the formula D = s * t, where D is the distance, s is the speed, and t is the time.
In this case, the bus traveled at a speed of 45 km/h for 5 hours. Plugging in these values into the formula, we get D = 45 km/h * 5 hours = 225 km.
Therefore, the bus traveled a distance of 225 km.
