Answer:
20.
Step-by-step explanation:
That's the correct answer
Explanation:
An <em>explicit function</em> returns a value based only on the arguments given.
y = f(x)
__
A <em>recursive function</em> returns a value based on the arguments given and on other values of the function.
y = f(x, f(g(x))
The function rule that relates the number of miles traveled to the hours driven is d = 55t
<h3>What is speed?</h3>
Speed is the ratio of distance traveled by a body to the time taken.
The formula for calculating distance is expressed as:
Given that the speed is 55 miles per hour
55 = d/t
Cross multiply
d = 55t
Hence the function rule that relates the number of miles traveled to the hours driven is d = 55t
