Question
The ratio between the speeds of two trains is 2 : 5. If the first train covers 350 km in 5 hours, then the difference between the speed (in km/h) of both the trains is?Options105180165350
Solution
The speed of the first train is calculated by dividing the distance covered by the time taken.
So, Speed of first train = 350 km / 5 hours = 70 km/h.
Given that the ratio of the speeds of the two trains is 2:5, we can say that if the first train's speed is 2x, then the second train's speed is 5x.
We know that 2x = 70 km/h (from the speed of the first train we calculated), so we can solve for x = 70/2 = 35 km/h.
Therefore, the speed of the second train is 5x = 5*35 = 175 km/h.
The difference in speed between the two trains is therefore 175 km/h - 70 km/h = 105 km/h.
So, the correct option is 105.
