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
[tex]= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\ miles\ per\ hour}\\\\[/tex]
= 1.2 hours
Therefore we can conclude that the time that taken for the two trains is 1.2 hours.

Answer:
1.2 hours
Step-by-step explanation:
Given data:
Speed of the westbound train = [tex]55 miles/hr[/tex]
Speed of the eastbound train = [tex]75 miles/hr[/tex]
Since the trains are moving in the opposite direction their relative speed becomes,
[tex]55 miles/hr +75 miles/hr=130 miles/hr[/tex].
Since, time = distance / speed
Now the time taken for the two trains to be 156 miles apart
[tex]time = \frac{156 miles}{130 miles/hr} \\=1.2 hours[/tex]
Hence, the time taken for the two trains to be 156 miles apart = [tex]1.2 hours[/tex]
