Question

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.

Answer 1

Answer: 2546/67=38

Explanation:

So in 26 hours she read 1742 pages so each hour she reads 67 pages each hour so 2546 in all you divid that by 67 and you get 38

Answer 2

38 hours

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
