Brainliest !A passenger train and a freight train leave at the same time from stations that are 270 km apart. The trains are travelling toward each other, and the rate of the passenger train is twice the rate of the freight train. If the trains pass each other in three hours, what is the rate of each train?

Passenger train 60 km/h.

Freight train 30 km/h.

Step-by-step explanation:

Let the rate of the freight train be x  km / hr the  passenger train's rate is 2x km/hr.

The combined speed = 3x km/hr, so we have the equation

speed = distance . / time

3x = 270 / 3

9x = 270

x = 30 km/h.

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
