Ariel read a total of 1742 pages over 26 hours. In all, how many hours of reading will Ariel have to do this week in order to have read a total of 2546 pages? Solve using unit rates.

38 hours

Step-by-step explanation:

Given:

Total number of pages read = 1742

Total hours = 26

We can find, average page read per hours,

Avg page read = Total number of pages read/Total hours

Avg page read = 1742/26 = 67 pages

So we know Ariel on average can read 67 pages in an hour.

Now, using the same formulae:

Avg page read = Total number of pages read/Total hours

67 = 2546/Total hours

Total hours = 2546/67

Total hours = 38 hours
