A train of `150 m` length is going toward north direction at a speed of `10 ms^-1`. A parrot flies at a speed of `5 ms^-1` toward south direction parallel to the railway track. The time taken by the parrot to cross the train is equal to.

Explanation

To solve the problem, we need to determine the time taken by the parrot to cross the train. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the scenario
- The train is moving north with a speed of \(10 \, \text{m/s}\) and has a length of \(150 \, \text{m}\).
- The parrot is flying south with a speed of \(5 \, \text{m/s}\).

### Step 2: Determine the relative speed
Since the train and the parrot are moving in opposite directions, we can find the relative speed of the parrot with respect to the train. The relative speed is the sum of their speeds:
