Question

Convert 500 kilometers per hour to miles per second. Show the calculation.

Answer 1

To convert kilometers per hour (km/h) to miles per second (mi/s), we can use the following conversion factors:

1 kilometer = 0.621371 miles
1 hour = 3600 seconds

Now, let's break it down step by step:

1. Convert kilometers per hour to miles per hour:
\[
500 \text{ km/h} \times 0.621371 \text{ miles/km} = 310.6855 \text{ miles/h}
\]

2. Convert miles per hour to miles per second:
\[
310.6855 \text{ miles/h} \div 3600 \text{ seconds/h} \approx 0.0869015 \text{ miles/s}
\]

So, 500 kilometers per hour is approximately **0.0869 miles per second**.
