Answer:
52 miles per hour
Step-by-step explanation:
Firstly, It is important to point out that it is Average speed. The Average speed throughout all the way the car traveled.
And this is may calculated by a simple formula or if you'd rather by a proportion. Let's pick this simple formula, what's going to be useful.
Let's do the math!
Average speed = Δs/Δt
Δs = Variation of Space (given in miles) =156 -0
Δt =Variation of Time (given in hours) =3-0
Average Speed = 156-0/3-0 =156/3 =52 miles per hour
It is important to say, Average speed, is a rate so it is given in miles per hour

Which Method Should Be Used to Solve a Quadratic Equation? Quadratic equations are of the form ax2 + bx + c = 0 where a, b and c are real numbers, a ≠ 0. Quadratic equations have two solutions, but it is possible that one solution may repeat. happy to help
Answer:
0.2287
Step-by-step explanation:
The computation of the probability that the automated manufacturing system runs for more than 18 hours without a failure is shown below:
P(X > 17) = 1 - P(X < 17)
= 1 - [1 - e^-18 ÷ 12.2]]
= 1 - [1 -0.228684984
]
= 0.2287
V+8*v-3
v+v=2v
8+-3=5
Equation would be: 2v*5 because you cannot combine unlike terms
