zeke and jay run the yd dash, and jay wins by 10 yards. of jay runs the race in 30 s, what is the rate of each person in yds/s? how long did it take zeke to run the race

Answer 1

jay wins the 100 yard dash in 30 seconds

That's 100/30 = 10/3 = 3 1/3 yards per second

Zeke was 10 yards behind doing 90 yards in 30 seconds which is 90/30 = 9/3 = 3 yards per second.

Zeke finishes the 100 yard dash in 33 1/3 seconds. In 3 1/3 seconds Zeke goes 10 yards 90+10 = 100 yards

Asafa Powell, from Jamaica, set the world record of 9.07 seconds for the hundred yard dash.

Average walking speed is about 5 mph which is about 2.4 yards per second. 100 yards at that speed would take 100/2.4 = about 41 seconds. 30 or 33 1/3 is maybe just a fast walk, not really running.

In international competitions, they don't do the 100 yard dash anymore. It's been replaced by the 100 meter dash.

Either way, 30 or 33 1/3 seconds isn't really a "dash," It's more of a trot or jog. Call it the 100 yard walk or stroll.

Answer 2

r = d / t

r_Jake = 100 yd / 30 sec

r_Zeke = 90 yd / 30 sec
