Answer 2

Answer:

Answer is C=1296

Step-by-step explanation:

The Speed of a Jet Flame is 240 metres per second, and the distance covered by it in one and a half hour is:

Jet Flame = 240 m/s

1 m/s = 3.6 km/h

240 m/s = 12.96 km/h

12.96 km/h + (12.96 / 2 = 6.48 km/h)

The Speed of the Jet Flame is 19.44 km/h

And the Distance Covered is 1296 meters
