I think they have calculated velocity of bullet with respect to car which velocity of bullet - velocity of car in m/s

So 300-50 =250m/s

And this speed×time will give distance

250×2 =500m

Soumya5887: 500/275 sec taken to hit one bullet

Soumya5887: 60 sec taken to hit 500/657×60

Soumya5887: Bullets

shreyamahajan: are see again unhone fraction ulti kardi

Soumya5887: Are ha

Soumya5887: Kyuki 500/275sec taken by 1 bullet

Soumya5887: 1second taken by 1÷500/275

Soumya5887: So it get reversed

Soumya5887: And 60 sec taken by 60 ×275/500

shreyamahajan: oh haan ty
