Question

a supersonic jet is flying west at one - third of its maximum speed. the jets top speed is 4,500 kilometers per hour. if the jets velocity remains constant, how much time will it take the jet to fly 3,000 kilometers? write your answer as a whole number. hours

Explanation:

Step1: Find the jet's current speed

The jet's top speed is 4,500 km/h, and it's flying at one - third of that speed. So the current speed \(v=\frac{1}{3}\times4500\) km/h.
\(\frac{1}{3}\times4500 = 1500\) km/h.

Step2: Use the formula \(t=\frac{d}{v}\) to find time

We know that distance \(d = 3000\) km and speed \(v = 1500\) km/h. Using the formula for time \(t=\frac{d}{v}\), we substitute the values: \(t=\frac{3000}{1500}\).
\(\frac{3000}{1500}=2\) hours.
