To calculate the time it will take to travel a certain distance at a given average speed, you can use the formula:
Time = Distance / Speed
In this case, the distance is 300 kilometers and the speed is 30 kilometers per hour. Plugging in these values into the formula, we get:
Time = 300 km / 30 km/h
Simplifying the expression, we find:
Time = 10 hours
Therefore, it will take approximately 10 hours to travel 300 kilometers at an average speed of 30 kilometers per hour.
