Answer:
Adam
Explanation:
Noah: 8 feet per second
Jessica: 358 feet / 34 seconds = 10.53 feet / second (just divide the feet / seconds.
Adam:
1 mile = 5280 feet
Adam runs 5280 / 444 seconds = 11.89 feet per second
Liz:
1 minute = 60 second.
Liz runs 592 feet / 60 seconds = 9.87 feet / second
Answer: Adam
Answer: Adam
Explanation: Here we just need to find the speed of each runner in a single unit of expression to compare them.
we know, [tex]Speed = \frac{Distance}{time}[/tex]
For,
Noah:
Distance= 8 feet
time= 1 sec.
∴ speed = 8 fps
Jessica:
Distance= 358 feet
time= 34 sec.
∴ speed = [tex]\frac{358}{34}[/tex] = 10.5294 fps
Adam:
Distance= 1 mile = 5280 feet
time= 444 sec.
∴ speed = [tex]\frac{5280}{444}[/tex] = 11.892 fps
Liz:
Distance= 592 feet
time= 1 min. = 60 sec.
∴ speed = [tex]\frac{592}{60}[/tex] = 9.867 fps
From the above results we find that Adam is the fastest runner.
