A patrol covers 3 blocks in 2 minutes. At this rate, how long to cover 9 blocks?

Explanation:
This question tests scaling a constant rate. If 3 blocks take 2 minutes, the pace is 3 blocks per 2 minutes, or 1.5 blocks per minute. To cover 9 blocks, you scale up by the same factor as the distance: 9 blocks is three times as far as 3 blocks, so the time is three times as long. 2 minutes × 3 = 6 minutes. Quick check: at 1.5 blocks per minute, 6 minutes yields 1.5 × 6 = 9 blocks. The other times would require a faster or slower pace than the given rate, so they don’t fit.
