Answer:
7 Minutes and 22.5 Seconds Per Mile
Step-by-step explanation:
58/8 = 7.375
Then you have to get the .375 into minutes.
0.375*60 = 22.5

we have

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side.


Rewrite as perfect squares


Answer:
4.5
Step-by-step explanation:
Put numbers in order, 1,3,3,4,5,8,9,12
Divide by 2 because there are 2 numbers
Because 4.5 is in the middle of 4 and 5 that is your median

Answer:
Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.
Step-by-step explanation:
second order reaction: The rate of reaction proportional to the square of the concentration of reactant.
For second order reaction

K is rate constant = 1.6×10⁻³M⁻¹hr⁻¹
a = initial concentration of reactant = 2.30 M
a-x = concentration of reactant after t h
t = time = 4.5 h
Putting the values in the above equation,





Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.
