Answer: Malcolm can read 25 pages in 1 hour if he maintains the same reading speed.
Explanation:
First, let's calculate how many pages Malcolm can read in 1 minute:
5 pages / 12 minutes = 0.4167 pages per minute (rounded to four decimal places)
To find out how many pages Malcolm can read in 1 hour, we need to multiply the number of pages he can read in 1 minute by the number of minutes in an hour:
0.4167 pages per minute * 60 minutes per hour = 25 pages per hour (rounded to the nearest whole number)
Therefore, Malcolm can read 25 pages in 1 hour if he maintains the same reading speed.
