Final answer:
To find out how far Nia will run, multiply her average speed of 5.8 mph by the time converted to hours (1.2 hours), which results in a distance of 6.96 miles.
Step-by-step explanation:
The question asks how far Nia will run if she maintains an average speed of 5.8 miles per hour for 1 hour and 12 minutes. To find the distance, we use the formula Distance = Speed × Time. First, we need to convert the time to hours since the speed is in miles per hour. One hour and 12 minutes is the same as 1 + (12/60) hours, which can be simplified to 1.2 hours.
Next, we calculate the distance by multiplying her average speed by the total time in hours:
Distance = 5.8 miles/hour × 1.2 hours = 6.96 miles.
The correct answer is B. 6.96 miles.
