Two trains, each of length `100 m`moveing in opposite direction along parallel lines, meet each other with speeds of `50 km h^(-1)` and ` 40 km h^(2)`. If their other with are `30 cm s^(-2)` and `20 cm s^(2)` and `20 cm s^(2)`, respectively, find the time they will take to pass each other.

Explanation

To solve the problem of two trains passing each other, we will follow these steps:

### Step 1: Convert speeds from km/h to m/s
The speeds of the trains are given in kilometers per hour. We need to convert them to meters per second for consistency in units.

- Train 1 speed:
\[
v_1 = 50 \, \text{km/h} = \frac{50 \times 1000}{3600} = \frac{50000}{3600} \approx 13.89 \, \text{m/s}
