Two trains leave the station at the same, one heading west and the other east. The westbound train travels at 55 miles per hour.

Mars2501 [29]

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

$= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\ miles\ per\ hour}\\\\$

= 1.2 hours

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