Answer:
200 km/hr
Step-by-step explanation:
We can find the speed by dividing the distance by the time taken for the trip.
[tex]\sf \boxed{Speed = \dfrac{distance }{time}}[/tex]
[tex]\sf r = \dfrac{300}{t}[/tex]
In the above equation, substitute t = 1.5 hours and find the train's rate.
[tex]\sf r = \dfrac{300}{1.5}\\\\= \dfrac{300*10}{1.5*10}\\\\= \dfrac{3000}{15}\\\\r = 200 \ kilometers \ per \ hour[/tex]
