The Vanderbloom family already traveled 200 miles on their vacation. The total distance that they will travel (d) is a function

allochka39001 [22]

Answer:

See explanation

Step-by-step explanation:

The question is incomplete. However, I'll ask and answer possible questions that emanate from the given parameter.

A possible question is: Write the given information as a function of distance.

We have that;

$Base\ Distance = 200$

$Time = t$

$Rate = r$

The function would be calculated as:

Base Distance + Rate * Time

Substitute values for Base Distance, Rate and Time

This gives:

$200 + r * t$

$200 + rt$

Hence;

$Distance = 200 + rt$

Another possible question is to determine the current distance travelled by the family at a rate of 80 miles per hour for 3 hours.

Here, we have:

$r = 80$

$t = 3$

Substitute these values in $Function = 200 + rt$

$Distance = 200 + 80 * 3$

$Distance = 200 + 240$

$Distance = 440$
