Julio walks 3 1/2 miles in 1 1/4 hours
Do you have a question?
I can not answer this.
To calculate Julio's speed, we can use the formula:
Speed = Distance / Time
Given that Julio walks 3 1/2 miles in 1 1/4 hours, we need to convert the mixed numbers to improper fractions:
3 1/2 = (2 * 3) + 1/2 = 7/2
1 1/4 = (4 * 1) + 1/4 = 5/4
Now, we can plug the values into the formula:
Speed = (7/2) / (5/4)
To divide fractions, we need to multiply the first fraction by the reciprocal of the second:
Speed = (7/2) * (4/5)
Simplifying the multiplication:
Speed = (7 * 4) / (2 * 5)
Speed = 28 / 10
Now, we can simplify the fraction:
Speed = 2 4/10
Reducing the fraction to its simplest form:
Speed = 2 2/5
Therefore, Julio's speed is 2 2/5 miles per hour.
To find out Julio's speed, we need to divide the distance he walked by the time it took him. In this case, Julio walked 3 1/2 miles in 1 1/4 hours.
Step 1: Convert the mixed numbers to improper fractions.
3 1/2 as an improper fraction is (2 * 3) + 1 = 7/2.
1 1/4 as an improper fraction is (4 * 1) + 1 = 5/4.
Step 2: Divide the distance by the time.
7/2 miles ÷ 5/4 hours.
To divide fractions, we multiply the dividend by the reciprocal of the divisor.
(7/2 miles) * (4/5 hours).
Step 3: Simplify the fractions if possible.
7/2 multiplied by 4/5 is (7 * 4) / (2 * 5) = 28/10.
Step 4: Simplify the fraction further if possible.
The fraction 28/10 can be simplified by dividing the numerator and denominator by their greatest common divisor, which is 2.
28/10 = (28 ÷ 2) / (10 ÷ 2)
= 14/5.
So, Julio's speed is 14/5 miles per hour.
