Ralph and Liza are both driving from Los Angeles to Santa Fe. Ralph leaves at 7:00 and averages 60 mph (miles per hour) on the way. Liza leaves at 7:25 and averages 65 mph on the way. The situation is modeled by this system,
where x is the number of hours after Liza leaves and y is the distance each
will travel:

y = 60x + 25
y = 65x

How long after Liza leaves will she pass Ralph, and how far will they each
have traveled?

A. Liza will pass Ralph after 4 hours, and they each will have traveled
260 miles.

B. Liza will pass Ralph after 3 hours, and they each will have traveled
205 miles.

C. Liza will not pass Ralph, because she will never catch up with him.

D. Liza will pass Ralph after 5 hours, and they each will have traveled
325 miles.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Ralph and Liza are both driving from Los Angeles to Santa Fe.

Ralph leaves at 7:00 and averages 60 mph (miles per hour) on the way.

Liza leaves at 7:25 and averages 65 mph on the way.

The situation is modeled by this system will travel:

y = 60x + 25

y = 65x

where x is the number of hours after Liza leaves and y is the distance each

The time after Liza leaves will she pass Ralph will be

65x = 60x + 25

 5x = 25

   x = 5 hours

Then the distance covered by both after 5 hours will be

y = 65 (5)

y = 325 miles
