Question

let x represent the number of hours you read a book and y represent the total number of pages you have to read you already read 70 pages and can read 30 pages per hour . write an equarion relating x hours and y pages you read then predict the total nuber of pages you will have read after another 3 hours

Answer 1

Given:
x = number of hours
y = total number of pages
70 = number of pages already read
30 =number of pages read per hour

y = 30x

70 = 30x
70/30 = 30x/30
2 1/3 = x

You read 70 pages within 2 hours and 20 minutes.

y = 30x
y = 30(3)
y = 90

An additional 90 pages have been read after another 3 hours.

Total pages read.

y = 30(2 1/3) = 70 pages
y = 30(3)       = 90 pages
                         160 pages within 5 hours and 20 minutes.
