Set it up as a proportion. 14.25 miles is to 90 minutes as x is to 120 minutes.
We have to solve with like units of measure, so we have to change the hours to minutes before we can set up the proportion.
60 minutes= 1 hour
120 minutes = 2 hours
x= miles in 2 hours
14.25/90 = x/120
cross multiply
(14.25 * 120)= (90 * x)
1710=90x
divide both sides by 90
19= x
You could ride 19 miles in 120 minutes, so you could ride 19 miles in 2 hours.

Step-by-step explanation:
The value of the car after 11 years is $3137.18
<h3>
exponential function</h3>
An exponential function is in the form:
y = abˣ
where a is the initial value of y, b is the factor, y, x are variables.
Let y represent the value of the car in dollars after x years. From the table:
When x = 0, y = 12700, hence:
When x = 2, y = 9849, hence:
The exponential function is:
y = 12700(0.8806)ˣ
For 11 years:
y = 12700(0.8806)¹¹ = 3137.18
The value of the car after 11 years is $3137.18
