Question

Jenny is training for a race. She ran …– mile in 2 …"" minutes. How long does it take her to run each mile?

Answer 1

To find out how long it takes Jenny to run one mile, we assume she ran 1/2 mile in 2 1/2 minutes and use a proportion to calculate that she would take 5 minutes to run one mile.

Step-by-step explanation:

Jenny is training for a race and ran a certain distance in 2 1/2 minutes. However, the question seems to have a typo or missing information about the exact distance she ran. To calculate the time it would take her to run one mile, we need the specific distance she covered in those 2 1/2 minutes. If we assume she ran 1/2 mile (which seems likely given the context), we can set up a proportion to solve for the time it would take her to run one mile using the following steps:

1. Write down the known ratio, which is 1/2 mile per 2.5 minutes.
2. Set up the proportion to find the time it would take to run 1 mile: (1/2 mile / 2.5 minutes) = (1 mile / x minutes).
3. Cross-multiply to solve for x: 2.5 * 1 = 1/2 * x.
4. Divide both sides by 1/2 to find x.
5. Jenny would take 5 minutes to run one mile.
