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.
