    Because flash travel faster than thunder

    This due to the reason that light travels more faster than sound and it reaches us much sooner than sound so, even if lightning and thunder happen at the same time we receive light first

    This is because the speed of light is much more than the speed of sound

    Flash and thunder are produced are produced simultaneously,but the flash is seen first and then the sound is heard.This is because the speed of sound in air is very less than the speed of light in air.
    Speed of sound in air : 334ms⁻¹
    Speed of light in air : 3X10⁸ms⁻¹

    With the increase in Density of the medium, the speed of sound also increases.
