Question

It took Mary two hours and 30 minutes to read 110 pages in her book. What was Mary’s average reading rate in pages per hour?

Answer 1

The reading rate is 44 pages per hour

Explanation:

We are expected to solve for the reading rate in one hour.

Given data

number of pages= 110

time taken = 2hours 30 mins

we convert from minutes to hours

total time in hours= 2 +0.5hours= 2.5hours

Therefore it takes 2.5 hours to read 110 pages

the reading rate is 110/2.5

=44 pages per hour
