Two runners are competing in a race. One runner averages a pace of 7 minutes per mile and finishes the race in 28 minutes. The second runner finishes the race in 30 minutes. Which of the following is the pace of the second runner? A. 7 minutes, 15 seconds per mile
B. 7 minutes, 30 seconds per mile
C. 8 minutes, 15 seconds per mile
D. 8 minutes, 30 seconds per mile
You're right.
To find the pace of the second runner, we need to divide the total time taken by the distance covered.
First, let's find the distance covered by the first runner. We know that the first runner finishes the race in 28 minutes and averages a pace of 7 minutes per mile. So, we divide the total time by the pace:
Distance = Time / Pace = 28 minutes / 7 minutes per mile = 4 miles
Since both runners are competing in the same race, the second runner also covers the same distance, which is 4 miles. Now, let's find the pace of the second runner.
We know that the second runner finishes the race in 30 minutes.
Pace = Total Time / Distance = 30 minutes / 4 miles
Calculating the pace:
Pace = 7.5 minutes per mile
Therefore, the pace of the second runner is 7 minutes, 30 seconds per mile.
So, the answer is B. 7 minutes, 30 seconds per mile.
