Leo reads 13 pages in 1/3 hour?
a) what is the unit rate for page per hour
b)what is the unit rate for hours per page?

A) there are 3 times 1/3 in each hour: so we have to multiply the original number by 3: 3*13=39!!

b)

so, 13 pages in 1/3 of an hour

for this we have to divide the time needed for the 13 pages by 13:



so each page requires of an hour, which is approximately 1.5 minutes.
