Jason reads 120 pages in 45 minutes. If he continues to read at this rate, how many pages can be read in 1 hour?

Answer 1

120/45 = X/60, make the units the same, both sides pages per minutes

simplify the left side, dividing numerator and denominator by 5

24/9 = X/60

simplify the left side further, dividing top & bottom by 3

8/3 = X/60

multiply both sides by 3

8/1 = X/20

cross multiply X times 1 = 8 times 20

X= 8(20) = 160 pages in one hour

X = 8/3 of 60= 160
