Antonio read the first 60 pages of his book in 40 min at this rate how long should it take him to read the rest of his 210 page book

100 minutes or 1 hr 40 minutes

Step-by-step explanation:

rate = 60 pages/40 min = 3/2 pages per minute

his book is 210 pages

he read 60 pages

210 - 60 = 150 pages left to read

150 pages = 3/2 pages per minute * time

divide each side by 3/2

150 / (3/2) = time

150 * 2/3 = time

100 minutes

subtract 60 minutes (60 minutes = 1 hr)

1 hr 40 minutes

315 minutes

Step-by-step explanation:

Find the unit rate by dividing 60 by 40 which is 1.5. This mean that it takes Antonio a minute and a half to read one page. To find out how long it will take him to read the whole book, mulitply 1.5 by 210. Don't forget your unit!
