Answer:
the scenic route take 6h 40m
Step-by-step explanation:
first we have to make an equation that represents the relationship of each route
x = scenic route
y = direct route
x = y + y * 25/100
now we have to make an equation that represents the routes over time
x + y = 12
we replace the x by what is the same in the first equation (y + y * 25/100) in the second equation
x + y = 12
(y + y * 25/100) + y = 12
2 y + 0.25 y = 12
2.25y = 12
y = 12/2.25
if we spend this in minutes multiplying it by 60
y = 12/2.25 * 60 = 320 m = 5h 20m
x + y = 12
x + (5h 20m) = 12h
x = 12h - 5h 20m
x = 6h 40m
Answer: it’s a rational number because all rational numbers are fraction, also if you need help on your classes or work I can help you pass okay?

Required
How many times greater is y than x
To do this, we simply divide y by x
Apply law of indices
I used to look at the examples i can’t remember now what it is but look at the examples
Convert the dose into mg / lb
1 lb = .45 Kg
so the does = 6 * .45 = 2.7 mg/lb
so the daily dose of the patient is 93 * 2.7 = 251.1 mg
injections are available in 50mg per mL
to calculate the daily dose in mL 251.1 / 50 = 5 mL
