Questions: Convert the speed 25 mi / hr to feet / s

Transcript text: 7. Convert the speed $25 \mathrm{mi} / \mathrm{hr}$ to feet $/ \mathrm{s}$

Solution

Step 1: Convert miles to feet

1 mile = 5280 feet

\[ 25 \, \text{mi/hr} \times 5280 \, \text{ft/mi} \]

Step 2: Convert hours to seconds

1 hour = 3600 seconds

\[ 25 \, \text{mi/hr} \times 5280 \, \text{ft/mi} \div 3600 \, \text{s/hr} \]

Step 3: Simplify the expression

\[ \frac{25 \times 5280}{3600} \, \text{ft/s} \]

Step 4: Calculate the result

\[ \frac{132000}{3600} \approx 36.67 \, \text{ft/s} \]

$\boxed{36.67 \, \text{ft/s}}$
