Time = distance / speed
time = 395.1 / 79
time = 5.0 hrs
Well 9x40 would be the solution, so what is 9x40? That will be your answer.
Answer:
To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

Answer:
y = -
x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 2) ← 2 points on the line
m =
= - 
Note the line crosses the y- axis at (0, 4) ⇒ c = 4
y = -
x + 4 ← equation of line
