An air jet covers a certain distance at a speed of 144 km/h in 5 hours. To cover the same distance in 2 hours, what is the required speed of the air jet?

Correct option is C

Given:

Initial speed = 144 km/h
Time taken = 5 hours
Required time = 2 hours

Formula Used:
Distance = Speed × Time

Solution:​
Distance $$= 144 \times 5$$​ = 720 km
Required speed =$$\frac{720}{2} =$$​360 km/h
