Final answer:
To find out how many pages Grady can type in 1 hour, we can set up a proportion and solve for the unknown variable. Grady can type 2 pages in 1 hour.
Step-by-step explanation:
To find out how many pages Grady can type in 1 hour, we need to determine how many pages he can type in 1/3 hour first. We know that in 1/3 hour, Grady can type 2/3 of a page. To find out how many pages he can type in 1 hour, we can set up a proportion:
2/3 page = 1/3 hour
x pages = 1 hour
Cross-multiplying, we get:
2/3 * 1 hour = 1/3 * x pages
2/3 * 3/1 = x pages
6/3 = x pages
x = 2 pages
Therefore, Grady can type 2 pages in 1 hour.
