3 x 10 (with a small 6 at the top right of the ten). Hope this helped
Answer:
X = 45
Step-by-step explanation:
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:

15 < 20, so Johnny read faster. This is 5 pages faster per hour than Jacky.
I switched the x and y so it’s easier to see. The answer is (x-1)/(23).
