Elias has read 18 pages of a book. He will continue to read at an average rate of 4 5 5 4 page per minute. The total number of pages (p) Elias reads after m minutes can be represented by the equation p = 4 5 m + 18 p= 5 4 m+18. How many minutes will it take Elias to read a total of 39 pages?

26.25 minutes

Step-by-step explanation:

Given that :

Number of pages (p) read by Elias can be modeled by the function ;

p = 45m + 18

Where P = Number of pages ; m = number of minutes

Number of minutes it will take to read a total of 39 pages

p = 4/5m + 18

39 = 4/5m + 18

39 - 18 = 4/5m

21 = 4/5m

4m = 21 * 5

4m = 105

m = 105 / 4

m = 26.25
