Question 134470
Wanda has read 80 of the 118 pages in a book. It took her 2 hours, 40 min. It is now 8:30 pm. When will she finish?
:
Convert 2 hr 40 min to minutes. 2*60 + 40 = 160 min
She has 118 - 80 = 38 pages left to read
:
Use a ratio equation:
{{{38/80 = x/160}}}
80x = 38 * 160
x = {{{6080/80}}}
x = 76 min to read 38 pages: 1 hr 16 min
:
8:30 + 1:16 = 9:46 pm she should finish.
