If Jana can run 1 mile in 7.9 minutes, how long will it take her to run 2.5 miles.
2.5 * 7.9 = ________ minutes
19.75
Yes.
To find out how long it will take Jana to run 2.5 miles, we can use the concept of proportions. Let's set up a proportion using the given information:
1 mile is completed in 7.9 minutes.
So, we can set up the proportion:
1 mile / 7.9 minutes = 2.5 miles / x minutes
Here, x represents the time it will take Jana to run 2.5 miles.
To find the value of x, we can cross-multiply and solve for x:
1 mile * x minutes = 2.5 miles * 7.9 minutes
x = (2.5 miles * 7.9 minutes) / 1 mile
x = 19.75 minutes
Therefore, it will take Jana approximately 19.75 minutes to run 2.5 miles.
