Someone finished 3/5 of the 45 math problems he was assinged today. How much more time, to the nearest minute, will the rest of the problems take him to finish?
Here are the choices:
A. 18min
B. 27min
C. 32min
D. 43min
You haven't told us how long it took to finish the 3/5 of the problems that
he already worked. It is impossible to pick a remaining time when there
is nothing to compare.
