Write in miles per hour. Round to the nearest tenth.
211 ft/s
211ft/s * 1mi/5280ft * 3600s/hr = 143.86 mi/hr
To convert 211 ft/s to miles per hour, we need to use the conversion factor 1 mile = 5280 feet and 1 hour = 3600 seconds. Here are the steps to do the conversion:
Step 1: Convert ft/s to miles per second
To convert feet per second (ft/s) to miles per second (mi/s), we divide by the number of feet in a mile. So, we have:
211 ft/s ÷ 5280 ft = 0.04 mi/s (rounded to the nearest hundredth)
Step 2: Convert miles per second to miles per hour
To convert miles per second (mi/s) to miles per hour (mi/h), we multiply by the number of seconds in an hour. So, we have:
0.04 mi/s × 3600 s = 144 mi/h (rounded to the nearest tenth)
Therefore, 211 ft/s is approximately equal to 144 miles per hour (mi/h).
