Given the speeds of the runners below determine who runs the fastest jake runs 13 feet per second will runs 391 feet in 45 seconds jessica runs 1 mile in 592 seconds zach runs 747 feet in a minute

The answer to your question is: Will is the fastest

Step-by-step explanation:

Data

Jake runs  13 ft per second

Will runs 391 ft in 45 seconds

Jessica runs 1 mile in 592 seconds

Zach  runs 747 ft in a minute

Process

Jake

             speed = 13 ft/s

Will

             speed = 391 ft / 45 s

                       = 8.7 ft/s

Jessica

                1 mile  5280 ft

             speed =  5280 ft/ 592 s

                        = 8.9 ft/s

Zach

            speed = 747 ft / 60 s

                       = 12.45 ft/s

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
