$70 \ \frac{\text{miles}}{\text{hour}}$

$\frac{70 \ \text{miles}}{1 \ \text{hour}}$

$\frac{70 \ \text{miles}}{1 \ \text{hour}} \times \frac{5280 \ \text{feet}}{1 \ \text{mile}}$

$\frac{70 \times 5280 \ \text{feet}}{1 \times 1\ \text{hour}}$

$\frac{369600 \ \text{feet}}{1 \ \text{hour}}$

$\frac{369600 \ \text{feet}}{1\ \text{hour}} \times \frac{1 \ \text{hour}}{60 \ \text{minutes}}$

$\frac{369600 \times 1 \ \text{feet}}{1 \times 60\ \text{minutes}}$

$\frac{369600 \ \text{feet}}{60\ \text{minutes}}$

$\frac{6160 \ \text{feet}}{1\ \text{minute}}$

$\frac{6160 \ \text{feet}}{1\ \text{minute}} \times \frac{1 \ \text{minute}}{60 \ \text{seconds}}$

$\frac{6160 \times 1\ \text{feet}}{1\times60 \ \text{seconds}}$

$\frac{6160 \ \text{feet}}{60 \ \text{seconds}}$

$\frac{308 \ \text{feet}}{3 \ \text{seconds}}$

$\frac{308}{3} \ \frac{\text{feet}}{\text{second}}$

$102.667 \ \frac{\text{feet}}{\text{second}}$

==============================================================================================================
Answer:

So $70 \ \frac{\text{miles}}{\text{hour}} \approx {\color{red}102.667 \ \frac{\text{feet}}{\text{second}}}$

Note: this is approximate
