The average speed is the total distance divided by the total time. The total distance is 11 miles and the total time is 26 minutes. Thus, the average speed is <span class=\"math-container\"><img align=\"middle\" role=\"math\" class=\"math-img\" src=\"/api/assets/b6d6c6c4887e2062b8aa9220518aa11916c7979d8177511a7b0ef86f74619116\" alt=\"11 over 26\"></span> miles per minute. The question asks for the average speed in miles per hour, and there are 60 minutes in an hour; converting miles per minute to miles per hour gives the following:</p><p class=\"para_left\"><span class=\"math-container\"><img align=\"middle\" role=\"math\" class=\"math-img\" src=\"/api/assets/ca67a624fec9951918f8472043d51eb6e9fa00ff4ad55fb1ef5a4966e25be3b2\" alt=\"Average speed equals, the fraction 11 miles over 26 minutes, end fraction, times, the fraction 60 minutes over 1 hour, end fraction\"></span></p><p class=\"para_left nts-indent-80\">&nbsp;<span class=\"math-container\"><img align=\"middle\" role=\"math\" class=\"math-img\" src=\"/api/assets/031d546e4cd8c80547fa6d9e8c78f15709704f46ad66cdbf2a9753cdd851311f\" alt=\"which equals, the fraction 660 over 26, end fraction, miles per hour\"></span></p><p class=\"para_left nts-indent-80\">&nbsp;<span class=\"math-container\"><img align=\"middle\" role=\"math\" class=\"math-img\" src=\"/api/assets/71cc33cfecfe46f59d6fbf9a6879cee6cd7cabae1be7951c1b137fbbc8fdd5c4\" alt=\"which is approximately equal to 25 point 3 8 miles per hour\"></span></p><p class=\"para_left\">Therefore, to the nearest tenth of a mile per hour, the average speed of Paul Revere’s ride would have been 25.4 miles per hour.
