Question

Julio and Jake start their reading assignments the same day. Jake is reading a 168 page book at a rate of 24 pages per day. Julio’s book is 180 pages long and his reading rate is 1 1/4 times Jake’s rate. After 5 days, who will have more pages left to read? How many more? Explain your reasoning.

Answer 1

jake is reading a 168 page book at a rate of 24 pages per day
x number of days

168 - 24 x = 168 - 24(5 ) = 48


Jake will have 48 more pages to read



Julio his reading rate is 1 1/4 times Jake’s rate = 5/4 (24) = 30

julio’s book is 180

180 - 30(x) = 180- 30(5)= 180-150= 30 pages left to read

How many more?

48 -30 = 18 more pages
