Question : 16 [SSC CPO S.I.2010]
The speed of two trains are in the ratio 6 : 7. If the second train runs 364 km in 4 hours, then the speed of first train is
a) 72 km/hr
b) 78 km/hr
c) 84 km/hr
d) 60 km/hr
Answer »Answer: (b)
Using Rule 1,Distance = Speed × TimeSpeed = $\text"Distance"/\text"Time"$ , Time = $\text"Distance"/\text"Speed"$1 m/s = $18/5$ km/h, 1 km/h = $5/18$ m/s
Speed of second train
= $364/4$ = 91 kmph
7x ≡ 91
6x ≡ $91/{7x}$ × 6x ≡ 78 kmph
