Answer:

approximately 38.89 m/s.

Step-by-step explanation:

To calculate the average speed, you can use the formula:

Average Speed = Distance / Time

Given:

Distance = 28 km

Time = 12 minutes = 12/60 hours = 0.2 hours

Now, plug in the values:

Average Speed = 28 km / 0.2 hours = 140 km/h

To convert the average speed from km/h to m/s, you can use the conversion factor: 1 km = 1000 m and 1 hour = 3600 seconds.

Average Speed = (140 km/h) * (1000 m/km) / (3600 s/h) ≈ 38.89 m/s
