A scanner scanned 63 photos in 9 minutes. If it scans photos at a constant rate, it can scan
photos in 21 minutes. (3 points)
To find the rate at which the scanner can scan photos, we can divide the total number of photos scanned by the time taken:
Rate = Number of photos / Time
Rate = 63 photos / 9 minutes
Rate = 7 photos/minute
Therefore, the scanner can scan photos at a rate of 7 photos/minute.
