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?
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?
Solution
Step 1: Find the speed of the first train.
The speed of the first train can be calculated using the formula: Speed = Distance/Time.
Given that the first train covers 350 km in 5 hours, its speed is 350/5 = 70 km/h.
Step 2: Find the speed of the second train.
The ratio between the speeds of the two trains is 2:5. This means that the speed of the second train is 5/2 times the speed of the first train.
So, the speed of the second train is 5/2 * 70 = 175 km/h.
Step 3: Find the difference in speed.
The difference in speed between the two trains is 175 - 70 = 105 km/h.
So, the difference in speed between the two trains is 105 km/h.
