First, convert 125 kilometers to miles (1 kilometer = 0.621371 miles), so 125 kilometers = 125 * 0.621371 = 77.671375 miles. Then, to find the time in hours, divide the distance by the speed: 77.671375 miles / 18.5 miles per hour = 4.2 hours. Finally, convert hours to minutes by multiplying by 60 (since there are 60 minutes in an hour): 4.2 hours * 60 minutes/hour = 252 minutes.
