We can have two d = rt equations.
d = 40 t
d = 50 (9 - t)
We know the distance is the same, so we can just set the equations equal to each now.
40 t = 50 (9 - t)
40 t = 450 - 50 t
90 t = 450
t = 5
So, Terrell took 5 hours going 40 mph, and 4 hours going 50 mph. 5 * 40 gives us 200 miles one way.

second one is square bas pyramid
third one is triangle base pyramid
Slope = (7-3)/(5-2) = 4/3
<span>passes through the points (2,3) and (5,7).
so
y = mx + b
3 = 4/3(2) + b
3 = 8/3 + b
b = 3 - 8/3
b = 9/3 - 8/3
b = 1/3
equation
y = 4/3x + 1/3</span>
