Assuming the pieces are not rearranged so that more than one piece is cut at a time, then:
5 pieces requires cuts, so each cut takes 20 minutes/4 each.
10 pieces require 9 cuts, therefore they will take 20/4 × 9 minutes = 45 minutes.

48 = 300 1____x If it takes 1 minute to grade 48 then it will take "x" amount of minutes to grade 300. The first fraction has to equal the second fraction when they are cross multiplied together. 1 times 300 has to equal 48x. Divide both by 48 and you will get x = 6.25 minutes (6 and a quarter minutes) which equates to six minutes 15 seconds.
