160/4 = p/6
Cross-multiply the propportion:
160 x 6 = 4p
Divide each side by 4:
p = 40 x 6 = 240 pages
You do 160/4 to find one pages time.
This is 40 pages.
Then you do 40 x 6 to find pages in 6 hours
Horace can read 240 pages in 6 hours. This is determined by calculating his reading speed of 40 pages per hour and multiplying by 6 hours. Therefore, 40 pages/hour multiplied by 6 hours equals 240 pages.
