Answer:

Jay's speed-7.333 yd/s

Zeke's speed- 7.0 yd/s

Zeke's time-31.43 seconds

Step-by-step explanation:

-Speed is defined mathematically as distance over time.

-Given the distance as 220 yds and Jay's time as 30sec, her speed is:

#Given that  Jay wins the race by 10yds, it means that Zeke was at 210 yds when Jay finished:

-Find Jay's time at d=210 yds:

#Zeke's speed for the race can now be calculated    as:

#Time it takes for Zeke to finish:

Hence, it takes Zeke 31.43 seconds to complete the dash.
