10 km ÷ 2.5 hours = 4 km/h — This is Sara's record
7.5 km ÷ 2 hours = 3.75 km/h — This is Katerina's record
9.5 km ÷ 2.25 hours = 4.2 km/h — This is Candice's record
Therefore, the answer is Candice had the fastest average speed.
Answer:
y = -2
Step-by-step explanation:
10 -5y = 20 { subtract 10 from both sides}
-5y = 20 - 10
-5y = 10 {Divide both sides by (-5) }
y = 10/-5
