Question: if it takes 42 minutes to load 3 1/2 trucks, how many minutes will it take to load 6 1/2 trucks?
Answer: “78 minutes“
Explanation:
42/x = 3.5/6.5 => x = 42 * 65/35 = 6*13#. 42 minutes to load 3 1/2 trucks, then 42 / 3.5 = 12 minutes to load a one truck. 12 x 6.5 = 78 minutes and the Answer is 78 minutes.
