Question
![**Convert a Speed from Meters/Second to Miles/Hour**
To convert a speed of 40 meters per second into miles per hour, please follow the detailed steps below:
1. **Conversion Factors:**
- 1,000 meters (m) = 0.6214 mile
- 1 hour = 60 minutes
- 1 minute = 60 seconds
2. **Conversion Process:**
- First, convert meters per second to meters per hour:
\[
40 \text{ meters/second} \times 60 \text{ seconds/minute} \times 60 \text{ minutes/hour} = 144,000 \text{ meters/hour}
\]
- Then, convert meters per hour to miles per hour using the given conversion factor:
\[
144,000 \text{ meters/hour} \times \frac{0.6214 \text{ miles}}{1,000 \text{ meters}} = 89.5 \text{ miles/hour}
\]
3. **Final Step:**
- Report the speed to the nearest whole number (no decimals), which is 90 miles/hour.
This conversion allows you to understand the speed in a different measurement system commonly used in some countries.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe6b70c34-e044-4376-aa23-4cdb751fc707%2F7af98b82-0539-4c5a-8333-6628d4b833a0%2Fd7u4w7p_processed.png&w=3840&q=75)
