John is driving around town. when he reaches the gas station, he notes that he has traveled 20 miles. he reaches home 2 hours later and notes that he has traveled 30 miles.

if d represents the distance and t represents the time, in hours, john has traveled since the gas station, which of the following equations can be used to model this situation?

Step-by-step explanation:

The equation that will model this situation will be of the form

where is the time in hours john has traveled since the gas station, and   is the distance.

Now we know that John has already traveled 20 miles when he is at the gas station, this means at , ; or

Thus we have

.

Now we need to figure out

When John reaches home 2 hours later he notes that he has traveled 30 miles, which means he has traveled 30 - 20 = 10 miles; thus we have

Now we have the full equation:

answer: i guess 105 degrees?

step-by-step explanation:

yes.. it's proven to be 36.
