Jen was making cake pops for the bake sale. After 3 hours, she had completed half of the work. She called Maryna for help and together they finished everything in half an hour. How long would it take Maryna to finish the job alone if she replaced Jen after Jen baked for 3 hours?

Your answer is: t = (1/2 * 6/12) / (5/12) (which equals) t=3/5 or in decimal form t= 0.6

Step-by-step explanation:

It says, " After 3 hours, she had completed half of the work" it means it would take all together Jen 6 hours to do the entire job.

It says, " together they finished everything in half an hour", so that means Jen does an a little bit more work, [1/2 / 6] or 1/12 for the entire job , and Maryna does 5/12 of the whole job in 1/2 hr.

Then, the equation would have been (5/12) / (1/2) = (6/12) / t, and the time for  Maryna to finish on her own  portion she would be doing 6/12 (half) of the whole job.

So therefore Your answer is: t = (1/2 * 6/12) / (5/12) (which equals) t=3/5 or in decimal form t= 0.6 :)

Hope this helped : )
