Question

Given the speeds of each runner below, determine who runs the fastest.

Ron runs 12 feet per second.
Brooke runs 329 feet in 24 seconds.
Jessica runs 1 mile in 591 seconds.
Tony runs 645 feet in 1 minute.

Answer 1

Brooke with 13 ft/sec

Explanation:

Ron is (12 ft/second)

To figure out Brooke we have to divide 329 by 24 to figure out her feet per second.

329/24 = 13.7083 so already is ahead of Ron.

To figure out Jessica we must first figure out the length of a mile in feet to keep the feet per second denominator going.

1 mile= 5280 ft

so now we divide

5280/591 = 8.9340

So Jessica is not the fastest so Brooke still stands number 1.

For Tony we divide 645 by the number of seconds in one minute

there are 60 seconds in a minute so

645/60= 10.75

So the fastest is brooke.

Ron = 12 ft/sec

Brooke = 13 ft / sec

Jessica = 8 ft / sec

Tony = 10 ft/ sec
