Answer:
speeds of Juan and Tiauna are 0.1984 m/s and 0.1851 m/s respectively
Step-by-step explanation:
Given: Juan's time in the race was 5.04 seconds and Tiauna's was 5.40 seconds
Let speed of Juan and Tiana's be J m/s and T m/s respectively
In the race both Juan and Tiauna will cover equal distance. Therefore, the speed and time would have reciprocal relationship
Speed ∝ 1/Time
This means J = 1/5.04 m/s
J= 0.1984 m/
and, T = 1/5.40 m/s
T= 0.1851 m/s
Therefore, speeds of Juan and Tiauna are 0.1984 m/s and 0.1851 m/s respectively
