During a monsoon storm, Amit sees a flash of lightning in the sky and hears the thunder $4$ seconds later. If the speed of sound in air is $330$ m/s, how far away was the lightning strike from Amit?
$82.5$ m
$660$ m
$1320$ m
$2640$ m
Solution
Distance is calculated as $\text{speed} \times \text{time} = 330 \text{ m/s} \times 4 \text{ s} = 1320 \text{ m}$.
