Katherine and beatrice are 20 miles apart when they start moving towards each other. katherine runs at a constant speed of 5 mph and beatrice walks at a constant speed of 3 mph. how long does it take them to meet

2 hours and 30 minutes.

Step-by-step explanation:

Katherine and Beatrice are 20 miles apart and they start to move towards each other.

It is given that Katherine runs at a constant speed of 5 mph and Beatrice walks at a constant speed of 3 mph.

As they are moving towards each other, so the resultant speed of them will be (5 + 3) = 8 miles per hour.

So, they will cover 20 miles distance with this 8 mph resultant speed.

Therefore, the time they will take to meet each other will be hours i.e. 2 hours and 30 minutes. (Answer)

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
