You would have to go 40 Miles Per Hour.
Answer:
1) Length = 5.7
2) Midpoint = (0, 2)
3) Gradient = 1
Step-by-step explanation:
We are given the intervals as;
A(-2, -1) and B(2, 3)
1) Formula for length of interval is;
AB = √[(3 - (-1))² + (2 - (-2))²)]
AB = √(16 + 16)
AB = √32
AB = 5.66 ≈ 5.7
2) Midpoint of the interval is;
((-2 + 2)/2), (-1 + 3)/2
This gives; (0, 2)
3) gradient is the slope and it's given by;
m = (y2 - y1)/(x2 - x1)
m = (3 - (-1))/(2 - (-2))
m = 4/4
m = 1
