Slobs, can you answer my question when you're done?
Answer:
$205
Step-by-step explanation:
260 + (-55) is basically 260 - 55.
So 260 - 55 = 205.
Hope this helps!
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)
