Answer:
40mph
Step-by-step explanation:
Using D = rt, the current variables we have are
D = 20 miles
t = 30 minutes
Since the goal is rate, we alter the equation to r = D/t.
In addition, we have to convert minutes into hours so we can
r = (20 / 30)*2/2
r = (40/60)
60 minutes is converted into an hour so the rate <em>r</em> is 40 miles per hour.
r = 40/1

An exponential function is given by
Given two points, (m, n) and (p, q), we find the equation of the exponential function as follows:
From (1), we have:
Therefore, the equation of an exponential function given two points (m, n) and (p, q) is given by
[i.e. you can choose any set of points and substitute the values in the equation above to get the exponential equation]
