The two trains are moving away from each other, so their speeds should be added together to find the total speed at which they are moving apart. The eastbound train is moving at 75 miles per hour, and the westbound train is moving at 65 miles per hour. Adding these speeds together gives us a total speed of 140 miles per hour at which the two trains are moving apart.
To find the time it will take for the two trains to be 336 miles apart, we can use the formula:
SOS 58
X
Time = Distance / Speed
In this case, the distance is 336 miles and the speed is 140 miles per hour.
Plugging these values into the formula, we get:
Time = 336 miles / 140 miles per hour
Simplifying the equation, we find:
Time = 2.4 hours
Therefore, it will take 2.4 hours for the two trains to be 336 miles apart.
In summary, if two trains leave the station at the same time, one heading east and the other west, with the eastbound train traveling at 75 miles per hour and the westbound train traveling at 65 miles per hour, it will take 2.4 hours for the two trains to be 336 miles apart.
