Jacky read at the rate of 15 pages per hour. Johnny read at the rate of 1/3 of a pages per minute. Who was reading faster? By ho
o-na [289]
We can compare by converting Johnny's reading time into the same unit of Jacky's, hours.

There are 60 minutes in an hour, so use this:

\frac{1}{3} *  \frac{60}{1} = 20

15 < 20, so Johnny read faster. This is 5 pages faster per hour than Jacky.
