. Look at the following problem:
To get to the reunion, we drove a total of 504 miles in 9 hours. Find our average rate of speed. (Distance is the product of rate and time).
Write a paragraph explaining what strategy or strategies could be used to solve this problem. Be sure to include a way in which a variable equation could be implemented:
To solve this problem, we can use the formula for average rate of speed, which is distance divided by time. In this case, the distance is given as 504 miles, and the total time is given as 9 hours. We can represent the average rate of speed as a variable, say 'r'.
Using the formula, we can set up the equation:
r = 504 miles / 9 hours
Simplifying this equation gives the average rate of speed:
r = 56 miles per hour
Therefore, our average rate of speed for the journey to the reunion was 56 miles per hour.
