Final answer:
By multiplying the average speed of the bus (90 km/h) by the time spent traveling (5 hours), we find that the bus traveled a total distance of 450 kilometers.
Step-by-step explanation:
This asks us to calculate the distance a bus has traveled, given its average speed and the time of travel. To find the distance, we use the formula: distance = average speed × time. Since the bus traveled at an average speed of 90 km/h for 5 hours, we can calculate the distance as follows: Distance = 90 km/h × 5 h = 450 km. Thus, the bus traveled a total distance of 450 kilometers. Therefore, the bus covered a total distance of 450 kilometers during its 5-hour journey, illustrating the fundamental relationship between speed and time in determining travel distance.
