Answer:

54 minutes

Step-by-step explanation:

We can write a proportion to solve this problem. Put the number of pages over the minutes

27 pages 324 pages

-------------- = ---------------

4.5 minutes x minutes

Using cross products

27 * x = 324 * 4.5

27x = 1458

Divide each side by 27

27x/27 = 1458/27

x =54

Lelechka [254]

If you add the two numbers, 10 +8 is 18. The fractional parts are 1/4 and 2/4 which equals 3/4. So the total length is 18 and 3/4 feet.
