Question

Convert the speed of light, 3*10^8
meters/second (m/s), to miles/day
(mi/day).

Answer 1

1 day = 86,400 seconds

1 mile = 1,609.344 meters

Speed = (3 x 10⁸ m/s) x (86,400 s/da) x (1 mi/1,609.344 m)

Speed = (3 x 10⁸ x 86,400 x 1 / 1,609.344) (meter-sec-mile/sec-day-meter)

Speed = 1.61 x 10¹⁰ mile/day

Speed = 16.1 gigamiles per day
