The ratio between the speeds of two trains is $5: 6$. If the second train covers 600 km in 5 hours, then what is the speed of the first train in km/h ?
Answer & explanation
Correct answer: option 2
The ratio between the speeds of two trains is 5:6. If the second train covers 600 km in 5 hours, then what is the speed of the first train in km/h ?
Ratio of speeds of two trains is 5 : 6
We know that, Speed = D/t
D = Distance
t = time
Let speed of the trains be 5x and 6x
So, 6x = 600/5 = 120
Now, 5x = 120 × 5/6 = 100km/h
