A person walk 1 mile everyday for exercise,she leaves at 9:00 am and returns to her front porch at 9:25 am.What is the average speed of her daily walk?
To find the average speed of the person's daily walk, we need to divide the total distance by the total time taken.
In this case, the person walks 1 mile each day and takes 25 minutes to complete the walk.
To calculate the average speed, you can use the formula:
Average Speed = Total Distance ÷ Total Time.
Plugging in the values we have:
Average Speed = 1 mile ÷ 25 minutes.
Now, we need to convert the time from minutes to hours, since speed is typically measured in miles per hour. There are 60 minutes in an hour, so:
Average Speed = 1 mile ÷ (25 minutes ÷ 60 minutes per hour).
Simplifying the equation:
Average Speed = 1 mile ÷ (25/60) hours.
Now, divide:
Average Speed ≈ 1 mile ÷ (25/60) hours ≈ 1 mile ÷ (5/12) hours.
To divide by a fraction, we flip the fraction and multiply:
Average Speed ≈ 1 mile × (12/5) hours ≈ 12 miles ÷ 5 hours.
Thus, the average speed of the person's daily walk is approximately:
Average Speed ≈ 12 miles ÷ 5 hours ≈ 2.4 miles per hour.
