Answers
Answer:
1,485m
Explanation:
Speed=D/T
=> 330=D/4.5
=>D=4.5×330
=>D=1485m
Given : During a thunder storm, the thunder is heard 4.5 seconds after the flash of lightning is seen.
if the speed of sound is 330m/s,
To find : the distance at which lightning took place
Solution:
thunder is heard 4.5 seconds after the flash of lightning is seen
speed of sound is 330m/s,
We can ignore the time of flash to travel as it will be in nano seconds
Hence Directly using Distance = speed x time
= 330 x 4.5
= 1485 m
distance at which lightning took place = 1485 m or 1.485 km
