The ratio between the speed of two trains is 5:6. If the second train runs 540 km in 6 hours, then the speed of the first train is:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 75 kmph
The ratio 5 : 6 means the first train’s speed is \(\frac{5}{6}\) of the second train’s speed.
Speed of the second train \(\displaystyle =\frac{540}{6}=90\) kmph
Speed of the first train \(\displaystyle =\frac{5}{6}\times90=\) 75 kmph
