I used Google to get that. But if you actually want to LEARN how to do it, pay attention. Convert 48 minutes to hours by dividing by 60 (minutes per hour). That gives you 0.8. So, 4 hours and 48 minutes is the same as 4.8 hours (4 + 0.8). Now, divide the distance, 203 km, by the time, 4.8 hours, which gives you your answer in km/hr.
1 minute = 60 seconds 1 hour = 60 mins → 45 mins 45 seconds = 45 + 45/60 mins = (45 + 45/60)/60 hours = 61/80 hours distance = speed × time → distance = 56 mph × 61/80 hours = 42.7 miles.
At 60 miles per hour, six hours. At 30 miles per hour, twelve hours.
