To calculate the average speed of the horse in miles per hour, holding the all-time record for running a 2-kilometer race in 1 min and 59.4 sec, we do the necessary conversions over distance from kilometers to miles and over time from minutes and seconds to hours.
The average speed thus calculated is 393.2722 miles per hour.
The average speed of any object is the ratio of the total distance the object travels, and the total time taken by the object to cover that distance.
Thus, Average speed = Total Distance/Time taken.
In the question, we are informed that a horse holds the all-time record for running a 2-kilometer race in 1 min and 59.4 sec.
We are asked for the necessary conversions required to calculate the average speed of the horse for the race in miles per hour.
The necessary conversions that will be required will be:
Distance: 2 kilometers to miles.
Time: 1 minute 59.4 secs to hours.
To convert from kilometers to miles, we follow the conversion rate:
1 kilometer = 0.621371 miles.
Thus, distance = 2 kilometers = 2 * 0.621371 miles = 1.24274 miles.
For the time, we first convert seconds to time, using the conversion rate:
1 second = 1/60 minutes,
Therefore, 59.4 seconds = 59.4/60 minutes = 0.99 minutes.
Thus, the total time = 1.99 minutes.
To convert from minutes to hours, we follow the conversion rate:
1 minutes= 1/60 hours.
Thus, time = 1.99 minutes = 1.99/60 hours = 0.03316 hours.
Thus, the average speed of the horse = Distance/Time = 1.24274/0.003316 miles per hour = 393.2722 miles per hour.
Thus, to calculate the average speed of the horse in miles per hour, holding the all-time record for running a 2-kilometer race in 1 min and 59.4 sec, we do the necessary conversions over distance from kilometers to miles and over time from minutes and seconds to hours.
The average speed thus calculated is 393.2722 miles per hour.
