"To determine how much longer until both trains pass each other, we first need to calculate the distance traveled by each train from the time they departed until the current time.
Train A is traveling from Station A to Station B, a distance of 252.5 miles. It has been 8 minutes (or 8/60 = 0.1333 hours) since the trains departed. Therefore, the distance traveled by Train A can be calculated as:
Distance_A = Speed_A * Time = 124.7 mph * 0.1333 hours = 16.63 miles.
Similarly, Train B is traveling from Station B to Station A, also a distance of 252.5 miles. The time elapsed for Train B is the same as for Train A, so the distance traveled by Train B is:
Distance_B = Speed_B * Time = 253.5 mph * 0.1333 hours = 33.8 miles.
Now, we need to determine the remaining distance between the trains. Subtracting the distances traveled from the total distance gives:
Remaining distance = Total distance - (Distance_A + Distance_B)
= 252.5 miles - (16.63 miles + 33.8 miles)
= 252.5 miles - 50.43 miles
= 202.07 miles.
To calculate the time needed for both trains to pass each other, we can use the relative speed of the two trains:
Relative speed = Speed_A + Speed_B = 124.7 mph + 253.5 mph = 378.2 mph.
Time = Distance / Relative speed = 202.07 miles / 378.2 mph ≈ 0.5344 hours.
Since there are 60 minutes in an hour, we can convert the time to minutes:
Time = 0.5344 hours * 60 minutes/hour ≈ 32.06 minutes.
Therefore, it will take approximately 32.06 more minutes until both trains pass each other."
