Question: A student writes an essay of 1200 words in 2 hours. If they want to increase their writing speed by 50%, how many words can they write in the same time?
Options:
Correct Answer: 1800
Solution:
Current speed is 1200 words / 2 hours = 600 words per hour. Increasing by 50% gives 600 * 1.5 = 900 words per hour. In 2 hours, they can write 900 * 2 = 1800 words.
