Analyzing Runner Performance Metrics

The video tutorial explains how four friends completed a 5 km run with an average time of 24 minutes. It demonstrates how to determine the fastest runner by comparing each person's time to the average. Negative numbers indicate times below the average, meaning faster times. The tutorial shows how to convert times into decimals for easier comparison and orders the runners from slowest to fastest, concluding that Vlad is the fastest and Joselyn is the slowest.

What was the average time taken by the four friends to complete the 5 km run?

• 28 minutes

• 20 minutes

• 24 minutes

• 30 minutes

How is the fastest time determined in the context of this problem?

• By the lowest number compared to the average

• By the highest positive number

• By the highest number compared to the average

• By the number closest to zero

What does a negative number represent in the table of times?

• A time greater than the average

• A time equal to the average

• A time less than the average

• A time not recorded

Who had a time of -2 compared to the average?

• Bianca

• Vlad

• Joselyn

• Pedro

Which method can be used to compare the times more easily?

• Converting times to hours

• Converting times to percentages

• Converting times to decimals

• Converting times to fractions

What is Pedro's time compared to the average when converted to a decimal?

• 0.5 minutes above

• 1.5 minutes below

• 2.75 minutes above

• 2 minutes below

Who is the slowest runner according to the final ordering?

• Bianca

• Joselyn

• Vlad

• Pedro

Which runner is 1.5 minutes below the average time?

• Vlad

• Joselyn

• Pedro

• Bianca

What is the significance of a runner being 'below average' in terms of time?

• They are faster than average

• Their time is not recorded

• They are exactly average

• They are slower than average

In the final ordering, who is identified as the fastest runner?

• Bianca

• Vlad

• Joselyn

• Pedro
