At Cross Country, Tina can run 12 miles in 3 hours. How far can she run in 1 hour?
12 miles/3 hours = 4 miles/hour
To find out how far Tina can run in 1 hour, we need to calculate her speed using the given information.
Speed is calculated by dividing the distance traveled by the amount of time taken.
In this case, Tina can run 12 miles in 3 hours. So her speed can be calculated as:
Speed = Distance / Time
Speed = 12 miles / 3 hours
Speed = 4 miles/hour
Therefore, Tina can run 4 miles in 1 hour.
