Christine runs 3 miles in 25 minutes. At the same rate, how many miles would she run in 85 minutes?
Cross multiply and solve for x.
3/25 = x/85

samantha can run one mile in 8 minutes.at this rate,how long will it take for her to run 5 miles?
To find out how many miles Christine would run in 85 minutes, we need to determine her running rate in miles per minute.
We know that Christine runs 3 miles in 25 minutes. So, we can calculate her running rate by dividing the number of miles by the number of minutes:
Running rate = 3 miles / 25 minutes.
Now, to find out how many miles she would run in 85 minutes, we multiply her running rate by the number of minutes:
Miles run in 85 minutes = Running rate × 85 minutes.
Let's solve this equation:
Miles run in 85 minutes = (3 miles / 25 minutes) × 85 minutes.
Simplifying the equation:
Miles run in 85 minutes = (3 miles / 25 minutes) × (85 minutes / 1).
Now, we can cancel out the minutes:
Miles run in 85 minutes = (3 miles / 25) × (85).
Finally, we perform the multiplication to get the answer:
Miles run in 85 minutes ≈ 3.24 miles.
Therefore, Christine would run approximately 3.24 miles in 85 minutes at the same rate.
