A supersonic jet is flying west at one-third of its maximum speed. The jet's top speed is 4,500 kilometres per hour. If the jet's velocity remains constant, how much time will it take the jet to fly 3,000 kilometres?

Answer :

Answer:

2hrs

Explanation:

Given parameters:

Top speed of the jet = 4500km/hr

Distance  = 3000km

Unknown:

Time it will take = ?

Solution:

Velocity is the displacement divided by time.

        Velocity  = [tex]\frac{displacement}{time}[/tex]  

         Time  = [tex]\frac{displacement}{velocity }[/tex]  

 The jet flies at one - third its maximum speed;

  So, speed of the jet  = [tex]\frac{1}{3}[/tex] x 4500 = 1500km/hr

Time = [tex]\frac{3000}{1500}[/tex]   = 2hrs
