At the track meet, Paul, Bob, Ron, and Ed ran in the 200-meter dash. Paul’s time was 19.8 seconds. Bob finished the race in 19.75 seconds, and Ed finished in 19.57 seconds. Ron ran the race in 19.6 seconds. What was the average time for the 4 runners?
Just add up the 4 numbers and then divide by 4
To find the average time for the 4 runners, we need to add up all their times and then divide by 4 (since there are 4 runners).
Paul: 19.8 seconds
Bob: 19.75 seconds
Ed: 19.57 seconds
Ron: 19.6 seconds
First, let's add up all their times:
19.8 + 19.75 + 19.57 + 19.6 = 78.72
Next, divide the sum by 4:
78.72 / 4 = 19.68
Therefore, the average time for the 4 runners is 19.68 seconds.
To find the average time for the 4 runners, you need to add up the times of each runner and divide the sum by the total number of runners.
Let's calculate it step by step:
1. Add up the time of each runner:
Paul: 19.8 seconds
Bob: 19.75 seconds
Ed: 19.57 seconds
Ron: 19.6 seconds
Total time: 19.8 + 19.75 + 19.57 + 19.6 = 78.72 seconds
2. Divide the total time by the number of runners (4 in this case):
Average time = Total time / Number of runners
Average time = 78.72 / 4
Average time ≈ 19.68 seconds
Therefore, the average time for the 4 runners is approximately 19.68 seconds.
