The ratio between the speed of two trains is 3 : 5, if the first train covers 450 kms. in 3 hours, then the speed of the second train is?

250 200 150 300

250

Speed of first train = \(\frac{450}{3}\)  = 150 km/h Speed Ratio:-   S1 :  S2 = 3 :  5 ATQ, 3R =150 km/hr 1R = 50 km/hr Speed of 2nd train = 5R = 5× 50 = 250  km/hr
