To find the y-intercept of the equation, we will put 0 in for x, and find y.
So, y = 14.2 - 3.9(0)
y = 14.2
The answer is 22,440......4 miles is 21,120 feet....1/4 of a mile is 1,320 feet.... so when you add em up you get 22,440 feet
Answer:
I believe it is because it does not start at 0
Distance = r x t ===> t=d/r
Distance (after 2 hours driving @30mil/hr) = 2 x 30 = 60 Mil
To drive same distance (60) with r = 50, the time needed is 60/50 =1.2 hrs
