Given the speeds of each runner below, determine who runs the
fastest.
liz runs 13 feet per second.
ron runs 495 feet in 34 seconds.
katie runs 1 mile in 506 seconds.
will runs 666 feet in 1 minute.

Ron runs the fastest.

Step-by-step explanation:

To see who's the fastest you should convert everyone's speed into one unit (feet per second for this example).

Liz

13 feet per second (doesn't have to be converted).

Ron

He runs 495 feet in 34 seconds, so he runs 495 feet ÷ 34 ≅ 14.55882 feet per second.

Katie

1 mile = 5280 feet. She runs 5280 feet in 506 seconds, so she runs 5280 ÷ 506 ≅ 10.43478 feet per second.

Will

1 minute = 60 seconds. He runs 666 feet in 60 seconds, so he runs 666 ÷ 60 = 11.1 feet per second.

Results

Liz - 13 feet per second

Ron - 14.55882 feet per second

Katie - 10.43478 feet per second

Will - 11.1 feet per second

As the results show, Ron runs the fastest, Liz the second fastest, Will the third fastest and Katie the fourth fastest.
