Yoko runs
3
miles in
25
minutes. At the same rate, how many miles would she run in
20
minutes?
Let's use a proportion.
3/25 = x/20
Cross multiply and solve for x.
25x = 60
x = 2.4 miles
To find out how many miles Yoko would run in 20 minutes at the same rate, we can set up a proportion.
A proportion is an equation that states that two ratios are equal.
In this case, the ratio of miles to minutes stays constant, so we can set up the following proportion:
3 miles / 25 minutes = x miles / 20 minutes
To solve for x, we can cross-multiply and then solve for x:
3 miles * 20 minutes = 25 minutes * x miles
60 miles * minutes = 25 minutes * x miles
Now, we can divide both sides of the equation by 25 minutes to isolate x:
60 miles * minutes / 25 minutes = x miles
Simplifying, we have:
2.4 miles = x miles
Therefore, Yoko would run 2.4 miles in 20 minutes at the same rate.
To summarize:
Yoko would run 2.4 miles in 20 minutes at the same rate.
To find out how many miles Yoko would run in 20 minutes at the same rate, we can set up a proportion using the information given.
The proportion can be set up as:
3 miles / 25 minutes = x miles / 20 minutes
To solve for x, we can cross-multiply and solve for x:
25 * x = 3 * 20
25x = 60
Dividing both sides of the equation by 25:
x = 60 / 25
Simplifying the fraction:
x = 12 / 5
So, Yoko would run approximately 12/5 or 2.4 miles in 20 minutes at the same rate.
