Final answer:
To find the time to float 60 km down the Genesee River at 5 km/h, divide 60 by 5 to get 12 hours. No additional minutes are necessary; it takes exactly 12 hours.
Step-by-step explanation:
To calculate the time required to float down a river, we use the formula Time = Distance ÷ Speed. In this situation, the student is floating down the Genesee River which has an average flow speed of 5 km/h. To float a distance of 60 km, we divide the distance by the flow rate of the river:
- Time = 60 km ÷ 5 km/h = 12 hours
Since the answer is already in whole hours, there are no additional minutes required. Therefore, it will take 12 hours to float 60 km down the Genesee River at an average flow rate of 5 km/h.
