If we double the time of flight in projectile motion, the distance it covers becomes _____?

If we double the time of flight in projectile motion, the distance it covers becomes _____?

اگر ہم پرکشیپک تحریک میں پرواز کے وقت کو دوگنا کرتے ہیں تو ، جس فاصلے پر اس کا احاطہ ہوتا ہے وہ _____ بن جاتا ہے؟
Explanation

Horizontal range in projectile motion is directly proportional to time of flight when speed is constant.

So, doubling the time results in double the distance covered.
