Answer

95 feet.

Work Step by Step

We should convert 65 mi/h to feet/second. We can use unit-factor method for that. 65 mi/h = $\frac{65mi}{h}\times\frac{1760yd}{1 mi}\times\frac{3ft}{1 yd}\times\frac{1h}{60m}\times\frac{1m}{60s} = \frac{(65\times5280)ft}{(60\times60)s} \approx 95 ft/s$ We know, Distance =$ speed\times time = 95 ft/s \times 1s$ = 95 ft.
