    Answer:

    900pages=45minutes

    Step-by-step explanation:

    Step 1: Find the unit rate=how many pages he can type in 1 minute

    to find the unit rate,

    k=y/x

    y=400 pages

    x=20 min

    400/20=20 pages in 1 minute

    Step 2: Multiply the amount of pages by 45

    k times x = y

    20 times 45= 900 pages in 45 minutes

    So, it will take the secretary 45 minutes to type 900 pages.
