Question

a train is moving at a speed of 100 km per hour it takes 18 minuts to reach station what should be its speed if the train wants to reach the station in 15 minutes​

Answer 1

Answer:

120 km/hr

Step-by-step explanation:

speed=distance/time

100=D/18/60                                     ( 18 minutes = 18/60=3/10 hours )

distance= 30km

again, since the distance will remain constant, therefore,

speed=30/15/60

          =30/1/4

          =30*4

          =120 km/hr
