Two trains travelling along a straight track are heading towards each other, travelling at 90km/hr and 100km/hr. Drivers of both the trains apply brakes together when the train are 1.0km apart, decelerating each train at `2.0m//s^(2)`. Determine that whether the train accident will be averted.

Explanation

To determine whether the train accident will be averted, we need to calculate the stopping distances of both trains after the brakes are applied and compare the sum of these distances to the initial distance between the trains.

### Step-by-Step Solution:

1. **Convert Speeds from km/hr to m/s**:
- For Train 1 (speed = 90 km/hr):
\[
U_1 = 90 \times \frac{5}{18} = 25 \, \text{m/s}
