Adrienne walks at a rate of 3 miles an hour and James walks 1 mile per hour faster, so James walks 4 miles per hour. Adrienne walks for one hour longer than James, so call James’ time t and Adrienne’s time t + 1.
The distance is interesting. They both start from Town X and walk towards Town Y, but they don’t make it all the way to Town Y. James catches up to Adrienne before that. The question asks how far James walked at the moment that he catches up to Adrienne—so, wherever that is, they have both walked the same distance to get there.
Set up equations from the table.
The two equations are both equal to d, so set the left-hand sides equal to each other and solve for t.
James walked for 3 hours at a rate of 4 miles per hour, so James walked for 12 miles before catching up with Adrienne.
Answer: E
