Answer 1

brooke 14 feet in one sec

Explanation:

stephanie 12 feet 1 sec

liz 8 feet in 1 sec

will approx 6 feet in 1 sec

brooke 14 feet in one sec

Answer 2

Brooke

Explanation:

We can solve this by figuring out how far each person runs a second

Stephanie runs 12 feet a second so nothing needs to be done here

Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet

Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75

Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18

Brooke obviously runs the furthest in one second and therefore she's the fastest runner
