Question

sonia read165 pages of a book having 275 pages on 7-1/5?how long it will take her to read the rest of the book?

Answer 1

Hello,

Sonia completed 165 pages in 7.5 hours.

we calculate the number of pages that reads in 1 hour:
165:7.5=22 pages

we calculate thumber of pages left for reading :
275 -165 = 110 pages

we calculate how long it takes to read the remaining pages:
110:22= 5 hours

Then she will need 5 more hours to complete the book.

bye :-)
