John walked 4 1/2 miles on a park trail in 1 1/3 hours what was her average speed in miles per hour
To find the average speed, you need to divide the distance traveled by the time taken.
Step 1: Add the whole numbers and the fractions separately.
4 + 1 = 5
1/2 + 1/3 = (3/6) + (2/6) = 5/6
Step 2: Convert the mixed number (5 5/6) into an improper fraction.
5 + (5/6) = (5*6 + 5)/6 = 35/6
Step 3: Divide the distance (35/6 miles) by the time (1 1/3 hours).
35/6 ÷ 4/3
Step 4: Invert the divisor (4/3) and multiply.
(35/6) × (3/4) = (35/2) ÷ 4 = 35/8
Step 5: Simplify the fraction.
35/8 = 4 3/8
Therefore, John's average speed was 4 3/8 miles per hour.
To find John's average speed in miles per hour, we need to divide the total distance he walked by the total time it took him.
First, let's convert the mixed number 4 1/2 to an improper fraction. The whole number part, which is 4, can be multiplied by the denominator of the fraction (2) and then add the numerator (1). This gives us:
4 * 2 + 1 = 9
So, 4 1/2 is equal to 9/2.
Next, we need to convert the mixed number 1 1/3 to an improper fraction. Again, we multiply the whole number part (1) by the denominator of the fraction (3) and add the numerator (1). This gives us:
1 * 3 + 1 = 4
So, 1 1/3 is equal to 4/3.
Now, we can calculate the average speed. Divide the distance traveled (9/2 miles) by the time taken (4/3 hours) to get:
(9/2) / (4/3) = 9/2 * 3/4 = (9 * 3) / (2 * 4) = 27/8
Therefore, John's average speed is 27/8 miles per hour.
It's 3 3/8 or 27/8 or 3.375
My apologies for the error. You are correct. The average speed is 3 3/8 miles per hour, which is equivalent to 27/8 or 3.375.
To find the average speed, we need to divide the total distance traveled by the total time taken.
Total distance = 4 1/2 miles
Total time = 1 1/3 hours
To add 1/3 to 1, we need to find a common denominator. The common denominator for 1 and 3 is 3.
1 1/3 = 3/3 + 1/3 = 4/3
Total time = 4/3 hours
Average speed = Total distance / Total time
Average speed = 4 1/2 miles / 4/3 hours
To divide a fraction by another fraction, we need to multiply the first fraction by the reciprocal of the second fraction.
Average speed = 4 1/2 miles * 3/4 hours
Average speed = 4 * 3/2 * 4/3 miles/hour
Average speed = (4 * 3)/(2 * 4) miles/hour
Average speed = 12/8 miles/hour
Average speed = 3/2 miles/hour
Therefore, John's average speed was 3/2 miles per hour.
