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
