Multiple Representations The two fastest times for swimming the English Channel belong to Petar Stoychev and Yvetta Hlavacova. Petar's average speed was 265 feet per minute. Yvetta's average speed was 249 feet per minute.

a. Tables Complete the table of ordered pairs in which the x-coordinate represents the time and the y-coordinate represents the total distance swum in 1, 2, 3, 4, and 5 minutes.

b. Graph each set of ordered pairs on the coordinate plane.

c. Algebra Write an equation for each swimmer to find the number of feet swam d in any number of minutes t.

d. Numbers If Petar Stoychev swam the Channel in 6 hours, 57 minutes, and 50 seconds., approximately how wide is the English Channel?

(Hint: 1 mi = 5,280 ft)
