84. Area of a triangle is (base x height) / 2
The time that taken for the two trains is 1.2 hours.
The computation of the time taken for the two trains is shown below:
Given that
The westbound train travels 55 miles per hour.
And, the eastbound train travels 75 miles per hour.
So, the total speed is
= 55 miles per hour + 75 miles per hour
= 130 miles per hour
The distance is 156 miles
So, the time taken is

= 1.2 hours
Therefore we can conclude that the time that taken for the two trains is 1.2 hours.
