Question

Two cars are driving to the same place.

The first car starts 45 miles ahead of the second car and travels at an average speed
of 35 miles per hour.
The second car travels at an average speed of 55 miles per hour.
Which graph represents this situation and shows the number of hours it will take for
the second car to pass the first car?

Answer 1

top left

Explanation:

Answer 2

The graph in the upper left

Explanation:

We can answer this question by elimination.

The answer can't be the two graphs on the right, because the two lines will never cross.

It can't be the graph at the lower left, because this shows both cyclists starting at Mile 0.

It must be the graph in the upper left. It shows one cyclist starting 45 mi ahead of the other, with the faster cyclist catching up after about 2.5 h.
