Given the speeds of each runner below, determine who runs the
fastest.
liz runs 10 feet per second.
katie runs 345 feet in 25 seconds.
brooke runs 1 mile in 454 seconds.
will runs 596 feet in 1 minute.

Katie runs the fastest

Step-by-step explanation:

Just take each distance and divide it by the time

For Liz, 10 feet/ 1 second is 10 ft/sec. That's her speed.

For Katie, 345 feet/ 25 seconds is 13.8 ft/sec. That's her speed.

For Brooke, we first convert 1 mile into feet, which is 5280 feet. Then we do 5280 feet/ 454 seconds to get 12.4528 ft/sec as her speed.

For Will, we need to convert 1 minute into seconds, which is 60 seconds. Then we do 596 feet/ 60 seconds to get 9.9333 ft/sec as his speed.

Katie has the fastest speed out of all of them.
