A horse ran a distance of 12 furlongs in 144 seconds. What was the average speed.in miles per hour, that the horse ran? (1mile=8furlongs)

To find the average speed of the horse in miles per hour, we need to convert the distance from furlongs to miles and the time from seconds to hours.<br /><br />Given:<br />Distance = 12 furlongs<br />Time = 144 seconds<br /><br />Step 1: Convert the distance from furlongs to miles.<br />Since 1 mile = 8 furlongs, we can divide the distance by 8 to get the distance in miles.<br />Distance in miles = 12 furlongs / 8 = 1.5 miles<br /><br />Step 2: Convert the time from seconds to hours.<br />There are 3600 seconds in an hour, so we can divide the time by 3600 to get the time in hours.<br />Time in hours = 144 seconds / 3600 = 0.04 hours<br /><br />Step 3: Calculate the average speed in miles per hour.<br />Average speed = Distance in miles / Time in hours<br />Average speed = 1.5 miles / 0.04 hours = 37.5 miles per hour<br /><br />Therefore, the average speed of the horse was 37.5 miles per hour.
