To determine the time it would take someone to travel a certain distance at a given 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 these values into the formula, we have:
Time = 300 km / 30 km/h
Simplifying the equation, we find:
Time = 10 hours
Therefore, it would take someone traveling at an average speed of 30 kilometers per hour approximately 10 hours to cover a distance of 300 kilometers.
