Final answer:
Clara can type 8 sheets in an hour and a half.
Step-by-step explanation:
To find out how many sheets Clara can type in an hour and a half, we can use the given information:
Clara takes 3 hours to type 16 sheets.
To find the number of sheets Clara can type in one hour, we divide 16 by 3: 16 / 3 = 5.33.
Since we want to know the number of sheets in an hour and a half, we multiply the number of sheets Clara can type in one hour by 1.5: 5.33 * 1.5 = 8.
Therefore, Clara can type 8 sheets in an hour and a half.
