Final answer:
To find out how long it takes for Jim to walk 5 miles, we can use the information given. Jim walks 3 miles in 45 minutes, so his average speed is 3 miles per 45 minutes. Using this information, we can set up a proportion and solve for the time it takes to walk 5 miles.
Step-by-step explanation:
To find out how long it takes for Jim to walk 5 miles, we can use the information given. Jim walks 3 miles in 45 minutes, so his average speed is 3 miles per 45 minutes. To find his average speed per mile, we can divide the distance by the time: 3 miles / 45 minutes = 0.067 miles per minute.
Now we can use this average speed to find out how long it takes for Jim to walk 5 miles. We can set up a proportion: 3 miles / 45 minutes = 5 miles / x minutes, where x is the time it takes to walk 5 miles. Cross-multiplying, we get 3x = 45 * 5. Solving for x, we find that x = 75 minutes.
Therefore, it takes Jim 75 minutes to walk 5 miles.
