T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
<span>77.5% can also be written as 77.5/100, but if you're the mathematical notation police, people don't like decimals on a fraction, sooo, an equivalent form is: </span>
<span>
= (77.5)/(100) * (2/2)
= 155/200
= 31/40
= 0 31/40 </span>
1 is ur answer Step-by-step explanation:
You would just take .5x5 which would be 2.5 inches without the snow melting it would add up to 13.5in the last part with the tt I’m not sure but it follows the same principle .5x(Time)+the original amount will give you the answer
