To find out how far the car travels in one hour using proportional reasoning, you can set up a ratio based on the distance traveled in one minute and the total time in hours. Since there are 60 minutes in one hour, you can multiply the distance the car travels in one minute (0.75 miles) by the number of minutes in an hour (60 minutes) to find the total distance traveled.
Here's a step-by-step summary to solve the problem:
- Identify the distance traveled per minute: 0.75 miles.
- Determine the total time in minutes for one hour: 60 minutes.
- Set up the calculation: Multiply the distance traveled per minute by the total minutes in an hour:
\( \text{Total Distance} = 0.75 \text{ miles/minute} \times 60 \text{ minutes} \). - Calculate the result: \( 0.75 \times 60 = 45 \text{ miles} \).
Thus, the car travels 45 miles in one hour by using proportional reasoning.
