To determine the time it takes to travel a certain distance at a given average speed, we can use the formula:
Time = Distance / Speed
In this case, the distance is 54 km and the average speed is 120 km/h. Plugging these values into the formula, we have:
Time = 54 km / 120 km/h
Calculating this, we find:
Time = 0.45 hours
Since time is typically expressed in hours, we can convert the decimal part into minutes. 0.45 hours is equal to 0.45 * 60 = 27 minutes.
Therefore, it will take approximately 0.45 hours or 27 minutes to travel 54 km at an average speed of 120 km/h.
