Question 235600: please help me solve this word problem:
Maria can write a paper an average of 4 pages during a 90 min. class period. At this rate,how many hours will it take her to write 16 pages?
create the proportion then solve.
This is what I did: 4/90=16/x, then i multiplied them and then i divided the number I got to 4. I got:x=360. But my teacher got x=6... Please tell me how she got that.
thank you
