Yan has already finished 3/5 of the 45 math problems he was assigned today. Each math problem took him 1 4/5 of a minute to complete. If this pace continues, how much more time, to the nearest minute, will the rest of the problems take him to finish?

Answer:

He will finish the rest of the problems in 32.4 minutes.

Explanation:

Since we are given that Yan has completed 3/5 of 45 problems i.e.


(3)/(5)*45


27

Thus he has completed 27 problems

Remaining no. of problems are 45-27 = 18

Since he complete each problem in minutes =
1(4)/(5) =(9)/(5) =1.8

So, he completes 18 problems in minutes = 18 *1.8 = 32.4 minutes

Hence , He will finish the rest of the problems in 32.4 minutes.
