Think of it this way:
You are trying to make a ratio to the months with thirty days and the ones who don't.
So,
there are 4 months a year with 30 days.
That means that there are 12-4= 8 months a year that are not 40 days.
It said the months to 30 days first in the problem.
4:8
Divide each side by 4, since both are divisible by 4.
1:2
For every one month of 30 days, there are 2 months that do not have 30 days.
1 to 2 is your answer.
I hope this helps!

V = 20.88 km / h ( velocity )
d = 145 km ( distance )
Velocity formula: v = d / t
t = d / v ( time )
t = 145 km : 20.88 km/h
t = 6.94444 h
We have to multiply 0.94444 by 60 minutes.
0.94444 · 60 = 56.67 ≈ 56 minutes 40 seconds
Answer: It would take 6 hours 56 minutes and 40 seconds.

Step-by-step explanation:
Using the rule of exponents

His mistake was in subtracting 3 rather than - 3
Slope = rise/run = (change in y)/(change in x)
Slope = (4-6)/(0-(-4)) = (-2)/(4)
Slope = -1/2 = -0.5
