Hello, sweetnata1!

Two people leave by car from the same location, traveling in opposite directions.

One leaves at 2:00 pm, driving at 55 km/hr,

while the other leaves at 3:00 pm, driving at 45 km/hr.

At what time will they be 280 kilometers apart?

Did you make a sketch? Code:

A P S B
* ← ----------* ← ----- * ----------------- → *
: - - 55t - - : - 55 - : - - - 45t - - - - - :

At 2 pm, car A starts at S and drives west at 55 km/hr.

In the first hour, it drives 55 km to point P.

In the next *t* hours, it drives *55t* km more to point A.

At 3 pm, car B start at S and drives east at 45 km/hr.

In the next *t* hours, it drives *45t* km to point B.

The distance between A and B is to be 280 km.

And *there* is our equation! . (55t + 55) + 45t .= .280

Solve for *x* and answer the question.
