A college language class was chosen for a learning experiment. Using a list of 50 words, the experiment measured the rate of vocabulary memorization at different times during a continuous 6-hour 15 for 1sts6. Find the area between t study session. The average rate of learning for the entire class was inversely proportional to the time spent studying, and was given approximately by V' (t)- the graph of V' and the t-axis over the interval [2.4), and interpret the results The area between the graph of V" and the t-axis over the interval (2.4] is approximately (Round to the nearest whole number as needed) Interpret the results. Choose the correct answer below. GELE A. The area between the graph of V' and the t-axis over the interval [24] is the average number of words learned from t=2 hr to t=4 hr. OB.
