To convert miles per hour (mph) to feet per second (fps), you can use the conversion factors that 1 mile is equal to 5280 feet and 1 hour is equal to 3600 seconds.
First, convert 50 miles per hour to feet per second using the following calculation:
\[ \text{Speed in feet per second} = \text{Speed in miles per hour} \times \frac{5280 \text{ feet}}{1 \text{ mile}} \times \frac{1 \text{ hour}}{3600 \text{ seconds}} \]
Now, substituting 50 mph into the formula gives:
\[ \text{Speed in feet per second} = 50 \times \frac{5280}{3600} \]
Calculating the fraction:
\[ \frac{5280}{3600} \approx 1.46667 \]
Now multiply:
\[ 50 \times 1.46667 \approx 73.3335 \]
Rounding to the nearest whole number results in:
\[ \text{Speed in feet per second} \approx 73 \]
Therefore, 50 miles per hour is approximately 73 feet per second.
