Question

Alessandro painted 1/3 of a wall in 45 minutes. If he keeps painting at that same rate, how much longer will it take him to finish painting the wall?

Answer 1

Answer: time for job = 3/4 hr/job = 45 minutes to do the whole job.

Explanation:

You paint 1/3 of a wall in 1/4 hour. At that rate, how long will it take you to paint one wall?

---------

rate = (area/time)

------

rate = (1/3)/(1/4) = 4/3 job/hr
