Answer:
a) Lightning will strike Earth 1200 times in 12 seconds.
b) It takes 72.5 seconds for the lightning to strike the earth 7250 times.
Step-by-step explanation:
Hi
First of all, we are going to define the rate, so [tex]rate=\frac{\# \ of\ strikes }{time}[/tex], hence, [tex]rate=\frac{1000\ strikes}{10secs}=100\ strikes/sec[/tex].
a) Using formula we have, [tex]\#\ of \ Strikes=rate \times time=100\ strikes/sec \times 12sec=1200\ Strikes[/tex]
b) Using formula again we have, [tex]time=\frac{\#\ of \ Strikes}{rate} =\frac{7250strikes}{100 \ strikes/sec} =72.5\ secs[/tex]
