Question

Two trains leave the station at the same, one heading west and the other east. The westbound train travels at 55 miles per hour. The eastbound train travels at 75 miles per hour. How long will it take for the two trains to be 156 miles apart?

Answer 1

Answer:

1.2 hours

Step-by-step explanation:

Given data:

Speed of the westbound train = $55 miles/hr$

Speed of the eastbound train = $75 miles/hr$

Since the trains are moving in the opposite direction their relative speed becomes,

$55 miles/hr +75 miles/hr=130 miles/hr$.

Since, time = distance / speed

Now the time taken for the two trains to be 156 miles apart

$time = \frac{156 miles}{130 miles/hr} \\=1.2 hours$

Hence, the time taken for the two trains to be 156 miles apart = $1.2 hours$

Answer 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

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

= 1.2 hours

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