One lap around the track is equal to 1/8 of a mile. A horse ran a distance of 9 laps in 2 minutes and 30 seconds. What was the horse's average speed in miles per minute?
9 laps = 9(1/8) or 9/8 miles
speed = (9/8) / 2.5 minutes
= 1.125/2.5 mpm
= .45 miles/min
I don't get it
One lap around a track is one-eighth of a mile. A horse ran a distance of 11 laps in 3 minutes and 30 seconds. What was the horses average speed in miles per minute.
What is the answer
its 3.15
i need teHG ANSWER FOR MY MATH WORK NPW
To find the horse's average speed in miles per minute, we need to convert the distance ran into miles and then divide it by the time taken in minutes.
First, we need to convert the number of laps into miles. We know that one lap is equal to 1/8 of a mile, so to find the total distance in miles, we can multiply the number of laps by 1/8:
Distance in miles = 9 laps * (1/8 mile/lap)
Distance in miles = 9/8 mile
Now that we have the distance in miles, we can calculate the average speed by dividing it by the time taken in minutes. We are given that the time taken is 2 minutes and 30 seconds, which can be converted to minutes as follows:
Time in minutes = 2 minutes + (30 seconds / 60 seconds/minute)
Time in minutes = 2 minutes + 0.5 minutes
Time in minutes = 2.5 minutes
Finally, we can calculate the average speed by dividing the distance in miles by the time in minutes:
Average speed in miles per minute = (9/8 mile) / (2.5 minutes)
Average speed in miles per minute = 3.6 miles/minute
Therefore, the horse's average speed is 3.6 miles per minute.
