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

2hrs

Explanation:

Given parameters

Top speed of the jet = 4500km/hr

Distance  = 3000km

Unknown:

Time = ?

Solution:

Velocity is the displacement divided by time.

       Velocity  =    

        Time  =    

The jet flies at one - third its maximum speed;

 So, speed of the jet  =  x 4500 = 1500km/hr

Time =    = 2hrs
