Question

The two trains are moving in opposite directions to each other. The speeds of both trains are 105 km/hr and 120 km/hr. Find the relative speed of the two trains with respect to each other.
1. 100 km/hr
2. 15 km/hr
3. 220 km/hr
4. 225 km/hr

Answer 1

Correct Answer - Option 4 : 225 km/hr

Given:

Speeds of both trains = 105 km/hr, 120 km/hr

Formula used:

When two bodies move in opposite direction,

Relative Speed = Sum of Speeds

Calculation:

According to the question:

Relative Speed = Sum of Speeds

⇒ Relative Speed = (105 + 120) km/hr = 225 km/hr

∴ The relative speed of the two trains are 225 km/hr.
