Step 1
Given that the speed is 3.5 x 10^8 meters per second, we need to convert this to miles per hour. 1 meter is approximately equal to 0.000621371 miles. 1 hour is equal to 3600 seconds. First, convert meters per second to miles per hour: (3.5 x 10^8 Show more…

Often speed is given in miles per hour (mph), but in physics, you will almost always work in SI units. Therefore, you must convert mph to meters per second (m/s). Part C: What is the speed of a car going 1.000 mph in SI units? Notice that you will need to change from miles to meters and from hours to seconds. You can do each conversion separately: Use the facts that 1 mile = 1609 m and 1 hour = 3600 seconds. Express your answer in meters per second to four significant figures.
