1 mph = 0.44704 m /s

1 meter = 3.2808399 feet

65mph = 29.0576 m / s
65mph = 95.3333 ft / s

One hour = 3600 seconds.

Therefore 65 mph = 65 m/3600 seconds.

65/3600 = miles/second

= .018 miles/second.

For the second part, 1 mile = 5,280 ft.

Therefore 65 mph = (5,280 ft x 65) / hr

= 343,200 ft/hr

1 hr = 3600 seconds

343,200/3600 = 95.33 ft/sec
