Gabby can read 22 pages in 30 minutes. how long would it take her to read a 100 page book? write your answer in hours and minutes.

Well, first of all, what you have to do is compare; So
22 pages= 30 minutes
100 pages= y minutes
  I represented the unknown figure with y. Anyway, what you have to do now is cross and multiply. y multiplies 22 and 30 multiplies 100. That will be;
22 y= 3000 (22 multiplied by y is 22y)
  Next, you have to divide the both sides by 22. You have to do this because 22 is the only number attached to y, and you have to remove all that is attached. You have to divide because the relationship between 22 and y is multiplication. The opposite of multiplication is division. Anyway;
22y/22=3000/22
y= 136 hours 8 minutes.
  

She can read 22 pages in 30 minutes so that means 22 = 1 30minutes so lets divide 100/22 = 4.54 so now times 4.50 x 30 = 136.2 minutes

30 divided by 22= 1.36 
1.36 minutes for each page, to check 1.36x22= 29.92
1.36x100=  136 minutes.
Mary would need about 2 hours and 16 minutes to read a 100 page book.

22 pages = 30 mins
1 page = 30 ÷ 22 = 15/11 min
100 pages = 1500/11 mins

1500/11 mins ≈ 136 mins
136 mins = 2 hours 16 mins

136 minutes

22/30 = 100/x

22*4.54 = 100
30*4.54 = 136

136 minutes (2.27 hours)

Hope this helps!

136 minutes or 2 hours, these are both rounded to the nearest whole number

2 hours 26 minutes

Step-by-step explanation:

22 pages in 30 minute

1 page in 30/22 =1.36 minute

100 pages in 1.36*100 =136 minute = 2 hours 26 minutes

2 hours 26 minutes

Step-by-step explanation:

22 pages in 30 minute

1 page in 30/22 =1.36 minute

100 pages in 1.36*100 =136 minute = 2 hours 26 minutes
