The table below shows the distances and times it took Mary, Jake, Tina, and Jose to race across their school campus to their science class. Each student took a different path, causing their distances traveled to vary.
Students Distance (meters) Time (seconds)
Mary 400 45
Jake 425 50
Tina 375 55
Jose 390 55
Using the table, which student had the fastest average speed during the race?
Mary had the fastest average speed during the race, with an average speed of 8.89 m/s.
To determine which student had the fastest average speed during the race, we need to calculate the average speed for each student. Average speed is obtained by dividing the distance traveled by the time taken.
First, let's calculate the average speed for each student:
For Mary:
Average speed = Distance / Time = 400 meters / 45 seconds = 8.89 m/s
For Jake:
Average speed = Distance / Time = 425 meters / 50 seconds = 8.50 m/s
For Tina:
Average speed = Distance / Time = 375 meters / 55 seconds = 6.82 m/s
For Jose:
Average speed = Distance / Time = 390 meters / 55 seconds = 7.09 m/s
Comparing the average speeds, we can see that Mary had the fastest average speed during the race, with an average speed of 8.89 m/s.
To determine which student had the fastest average speed during the race, we need to calculate the average speed for each student. Average speed is given by the formula: average speed = distance / time.
Let's calculate the average speed for each student:
For Mary:
Average speed = Distance / Time = 400 meters / 45 seconds = 8.89 m/s
For Jake:
Average speed = Distance / Time = 425 meters / 50 seconds = 8.5 m/s
For Tina:
Average speed = Distance / Time = 375 meters / 55 seconds = 6.82 m/s
For Jose:
Average speed = Distance / Time = 390 meters / 55 seconds = 7.09 m/s
Comparing the average speeds, we can see that Mary had the fastest average speed during the race, with an average speed of 8.89 m/s.
