Step-by-Step Calculation Breakdown (500-Word Academic Essay)
Step 1: Compute Average Sentence Length (500 words across 25 sentences)
Avg Sentence Length = 500 ÷ 25 = 20.0 words per sentence (Optimal reading target: 15–20)
Step 2: Calculate Reading Duration at Standard Pace (225 WPM)
Reading Time = 500 ÷ 225 = 2.22 minutes (~2 min 13 sec)
Step 3: Calculate Speaking Duration at Keynote Pace (150 WPM)
Speaking Time=500 ÷ 150=3.33 minutes (~3 min 20 sec)
