The work done by the engine in a given time.  
Power is the time rate of change of energy, (which is another name for work, both measured in Joules)
So power = energy/time, with units of Joules/second.
Since you know energy per time, if you know the amount of time you can multiply power by time to get energy (work).

Anestetic [448]

Answer:

Explanation:

Speed of sound = 331 m /s

speed of jet = 7 .00 Mach = 7 times speed of sound

= 7 x 331 = 2317 m /s

distance to be covered = 5000 x 1000 = 5 x 10⁶ m

Time taken = distance / speed of jet

= 5 x 10⁶ / 2317

= 2.158 x 10³ s

= 35.96 minutes .
