(b)- 1815m
What is the answer
As speed is equal to distance upon time
Then distance is equal to speed multiplied by time
Here speed is 330m/s and time is 5.5 sec
330*5.5=1815
Thus ,the distance of the flash is 1815 m
Then distance is equal to speed multiplied by time
Here speed is 330m/s and time is 5.5 sec
330*5.5=1815
Thus ,the distance of the flash is 1815 m
