Answer 2

Calculation of the Distance Between the Buses

To calculate the distance between the two buses, we can use the formula:

Distance = Speed × Time

Let's calculate the distance between the buses after 15 minutes and after 20 minutes.

1. After 15 minutes: - The speed of one bus is 450 meters per minute. - The speed of the other bus is 480 meters per minute. - Therefore, the distance covered by the first bus after 15 minutes is 450 × 15 = 6750 meters. - The distance covered by the second bus after 15 minutes is 480 × 15 = 7200 meters. - The difference in distance between the two buses after 15 minutes is 7200 - 6750 = 450 meters.

2. After 20 minutes: - The speed of one bus is 450 meters per minute. - The speed of the other bus is 480 meters per minute. - Therefore, the distance covered by the first bus after 20 minutes is 450 × 20 = 9000 meters. - The distance covered by the second bus after 20 minutes is 480 × 20 = 9600 meters. - The difference in distance between the two buses after 20 minutes is 9600 - 9000 = 600 meters.

Therefore, the distance between the two buses after 15 minutes is 450 meters, and after 20 minutes, it is 600 meters.

Please note that the above calculations assume that the buses maintain a constant speed throughout the journey. Additionally, the given distances and speeds are rounded to the nearest meter.
