Jason leaves Detroit at 2:00 P.M. and drives a a constant speed west along I-90. He passes Ann Arbor, 40 mi from Detroit, at 2:50 P.M.
(a) Express the distance d traveled (in miles) in terms of the time t elapsed (in hours).
d(t) ?
(b) What is the slope of this line?

Hey, I did that today! WIth pretty much that timeline too.
And my name is Jason. Who are you and why do you know my schedule?

From Detroit to Ann Arbor, the time is
2:50 - 2:00
t = 50 minutes or
t = 5/6 hrs
the distance traveled is
d = 40 mi
thus, the rate r = d/t (from d = rt)
r = 40/(5/6) mi/hrs
r = 48 mi/hrs
Substitute this to the formula d = rt
d = (48)t
d = 48 t
The slope of this line (from y = mx + b) is
m = 48
^_^

a) d(t) = 48t
b) The slope of the line is 48 miles/hour

a.)
d(t) = (40/(50/60))t
d(t) = ((40/1)/(5/6))t
d(t) = ((40/1)*(6/5))t
d(t) = (240/5)t
d(t) = 48t
thats assuming the speed remains constant.
b.)
m = 48
