Solving an Equation for a Rate Problem Stu hiked a trail at an average rate of 3 miles per hour. He ran back on the same trail a
t an average rate of 5 miles per hour. He traveled for a total of 3 hours. The equation 3t = 5(3 – t) can be used to find the time it took Stu to hike one way. How long did it take Stu to hike the trail one way?
<span>2x - 3y - z Substitute the variables for the numbers provided for them </span><span>2(-2) - 3(3) - (-2) Multiply 2 by -2 -4 - 3(3) - (-2) Multiply -3 by 3 -4 - 9 - (-2) Subtract 9 from -4 -13 - (-2) Convert Subtract -2 from -13. It would be the same as adding 2 to -13. Final Answer: -11</span>
