Question

The distance from earth to the sun is 1.5 x 10^ 8 km. there speed of light is 2.997 x10^8 m/sec. Calculate time

Answer 1

Hi Tina,

Since speed = distance/time,

then time = distance/speed.

Remember to convert the distance units to the same unit.

1.5x10⁸ km x(1000m/1km) = 1.5x10¹¹ m

Then (1.5x10¹¹ m)/(2.997x10⁸ m/s) = 500 seconds.
