Question

Light travels at a speed of 3 x 108 m/s What is the speed of light in km/h? a 1.08 x 10 km/hr b 2.08 x 10km/hr c 5.08 x 10 km/hr d 3.08 x 10 km/hr​

Answer 1

V = 3.00E^8 m/s speed of light

1 m = 1.00E-3 km

1 h = 3600 s

V = 3.00E8 m/s * 1.00E-3 km / m * 3.60E3 s/h

V = 1.08E9 km/h

a) would be the closest but it is missing a superscript
