Step-by-step explanation: For this question, we just need to represent our proportions by day in form of fractions.
Step 1:
On Tuesday Jim reads 24 pages in 40 mins so we have

On Wednesday Jim reads 18 pages in 24 mins so we have

Step 2: Now all we need to do is to calculate the divisions and compare if they are equal or different

Final answer: As we can see above both proportions are different so the final answer is that the ratios of pages that Jim reads per minute on Tuesday and Wednesday are not proportional.
