To find out how long it would take Paul to walk a distance of 6.25 km with an average speed of 5 km/h, we can use the formula:
Time = Distance / Speed
Time = 6.25 km / 5 km/h
Time = 1.25 hours
Since time is typically measured in hours, we can convert the decimal part of the result (0.25) into minutes:
0.25 hours * 60 minutes/hour = 15 minutes
So, it would take Paul 1 hour and 15 minutes to walk a distance of 6.25 km at an average speed of 5 km/h.
