 
 <prompt> Keenan need write one essay wey go reach 1200 words. Her essay dey due by midnight. She dey write 400 words per hour for di first two hours. After dat, she dey write 200 words per hour. How many hours before di deadline she need start to finish on time? <response>: ```For di first two hours, Keenan write 800 words because 400*2=800.
After dat, she still need to write 400 words because 1200-800=400.
Since she dey write 200 words per hour, she go take 2 hours to write di last 400 words because 400/200=2.
So, she need to start 4 hours before di deadline because 2+2=4.

Di answer go be 4.```
