Answer:
The value is
Step-by-step explanation:
From the question we are told that
The total number of cars is
The number cars considered is
Generally the number of different top three finishes possible for this race of 35 cars is mathematically represented as
Add all the numbers then divide by how many dates there are.
Speed = Distance ÷ time
Speed upstream = 84 ÷ 7 = 12 km/h
Speed downstream = 84 ÷ 3 = 28 km/h
Speed in still water = 1/2(28 + 12) = 20 km/h
Answer: 20 km/h
2 1/4 = 9/4
(9/4)(8/5) = (9/1)(2/5) = 18/5 = 3 3/5 cups
