A car moves a distance of 600 km with uniform speed. The umber of hours taken for the journey is $\frac{2}{3}$ of the number representing speed in km/h. The time taken to cover the distance is:
Answer & explanation
Correct answer: option 4
Distance = Speed × Time
600 = \(\frac{2 }{3}\)a × a
a² = 900
a = 30
So , Time taken = \(\frac{2 }{3}\) × 30 = 20 hours
