The table shows how far a distance runner has traveled since the race began. what is her average speed, in miles per hour, during the interval 0.75 to 1.00 hours? time elapsed (hours) miles traveled (miles) 0.50 2.00 0.75 3.50 1.00 4.75 4.75 miles per hour 5.00 miles per hour 5.50 miles per hour 6.00 miles per hour

During the interval from 0.75 to 1 hour. the distance runner ran at an average speed of 5 miles per hour. The correct answer is B.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Time Elapsed (Hours) 0.50   0.75  1.00

Miles Traveled (Miles)  2.00 3.50  4.75

2. What is her average speed, in miles per hour, during the interval 0.75 to 1.00 hours?

For calculating the average speed of the distance runner during the race, we will use the following formula:

Average Speed = Miles Traveled/Time Elapsed

Average Speed 1st Interval = 2/0.5 = 4 miles per hour

Average Speed 2nd Interval = (3.5 - 2)/(0.75 - 0.5) = 1.5/0.25 = 6 miles per hour

Average Speed 3rd Interval = (4.75 - 3.5)/(1 - 0.75) = 1.25/0.25) = 5 miles per hour

During the interval from 0.75 to 1 hour. the distance runner ran at an average speed of 5 miles per hour. The correct answer is B.
