Thus, if only 20 carats of pure gold and 4 of alloy, it is 20 carats fine; if 22 carats of pure gold and 2 of alloy, 22 carats fine ; and if there be no alloy, it is 24 carats fine or pure gold. A carat is 4 grains. To compute the fineness of any gold coin from the foregoing table. RULE. As the weight of the coin, Is to its contents in pure gold, So is 24 carats, To the fineness required.

Ans. 5832 seconds : 17024 feet run. 2. A. leaves New Italy at 4 o'clock in the morning for Harrisburg, and goes at the rate of 6 miles an hour, without intermission: B sets out of Harrisburg for New Italy at 5 o'clock the same morning, and rides at the rate of 5 miles an hour constantly—the question is, whereabouts on the road will they meet, and at what time; the distance being 55 miles ?
