Molly walks 1 1/2 miles in 3/5 hour. What is the walking rate?
(1 1/2 mi)/(3/5 hr)
= (3/2 mi)/(3/5 hr) = 5/2 mi/hr
or, 2 1/2 mi/hr if you like mixed numbers
To find Molly's walking rate, divide the distance she walks by the time it takes:
Walking rate = Distance / Time
Given that Molly walks 1 1/2 miles in 3/5 hour:
Walking rate = 1 1/2 miles / 3/5 hour
To divide fractions, multiply the first fraction by the reciprocal of the second fraction:
Walking rate = 1 1/2 miles * (5/3 hour)
Next, convert the mixed number into an improper fraction:
Walking rate = 3/2 miles * (5/3 hour)
Now, multiply the numerators together and the denominators together:
Walking rate = (3 * 5) / (2 * 3) miles/hour
Simplify the fractions:
Walking rate = 15 / 6 miles/hour
Finally, divide the numerator by the denominator:
Walking rate ≈ 2.5 miles/hour
Therefore, Molly's walking rate is approximately 2.5 miles per hour.
To find Molly's walking rate, we need to calculate the number of miles she walks per hour.
First, we need to convert the time from 3/5 hour to 1 hour.
To do this, we divide 1 by 3/5:
1 ÷ (3/5) = 1 × (5/3) = 5/3
So 3/5 hour is equivalent to 5/3 hour.
Next, we divide the distance Molly walks, which is 1 1/2 miles, by the time, which is 5/3 hour:
1 1/2 ÷ (5/3) = (3/2) ÷ (5/3)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
(3/2) × (3/5) = 9/10
Therefore, Molly's walking rate is 9/10 mile per hour.
1.5/0.6 = x/1
Cross multiply and solve for x.
