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?
Answer & explanation
Correct answer: option 1
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
