Can anyone please help with this one?

The newest jet fighter, the F-22 Raptor, cruises at 1.5 times the speed of sound. The speed of sound is 1.24x10^3 km/hr. How many hours does it take for the F-22 to fly the 5.8x10^3 km from New York to Paris? Demonstrate the use of scientific method in your calculations.

Speed = distance/time or S = d/t

1.5(1240) = 5800/t

Solve for t.

I hope this helps.
