Question

a gun is being fired at equal interval of time if the 13th shot is fired 21 minute after the first at what interval is the gun being fired ?​

Answer 1

Answer:

so the answer is

every shot is being fired after 1.75 second

Step-by-step explanation:

here given

13th shot is fired at 21 minute

then

let the interval of time when the shot is fired = x

when the first shot was fired then time was 0 so when 13th shot was being fired = 12x

so interval X = 21/12 second

so X = 1.75 second
