A function has a property such as "one input must be mapped to exactly one output." An input is the x-value, and the output is, generally, the y-value. In this set of points above, the input 3 maps to 4 <em>and </em>12, and therefore is not a function.

Answer:
Distance B = 1275 kilometers.
Step-by-step explanation:
Let the two distances and time be A and B respectively.
Given the following data;
Distance A = 17 kilometers.
Time A = 8 minutes.
Distance B =?
Time B = 60 minutes.
First of all, we would find the constant speed;
Speed = distance/time
Substituting into the equation, we have;
Speed = 17/8
Speed = 2.125 km/m
Now, to find the distance B;
Distance B = speed * time
Distance B = 2.125 * 60
<em>Distance B = 1275 km</em>
