A black car and a green car are traveling at the same speed. The black car drives 3 hours. The green car drives 3.5 hours and go
es 25 miles farther than the black car. Use x for the speed of the cars. In the time the green car goes 3.5x miles, the black car goes 3x+25 miles. Which equation can be solved to find how fast the cars are going?
<em>The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = ½( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.</em>
