How many seconds does it take for lightning to strike 7250 times? It takes seconds for lightning to strike 7250 times.

Answer 1

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.

Explanation:

Hi

First of all, we are going to define the rate, so
`rate=(\# \ of\ strikes )/(time)`, hence,
`rate=(1000\ strikes)/(10secs)=100\ strikes/sec`.

a) Using formula we have,
`\#\ of \ Strikes=rate * time=100\ strikes/sec * 12sec=1200\ Strikes`

b) Using formula again we have,
`time=(\#\ of \ Strikes)/(rate) =(7250strikes)/(100 \ strikes/sec) =72.5\ secs`
