Problema Solution
While doing her homework Marcie noticed that it took her 14.5 minutes to complete 13 problems. Her assignment has 65 problems and she has 1/5 of it done. How many minutes will it take her to finish?
Answer provided by our tutors
65 problems, 1/5 of which is done, means
65. / 5. =13 problems done
65-13=52 problems remain
14.5 minutes for 13 problems:
(52/13)*14.5 = 58 minutes to finish
