Two trains are on the same track heading for each other they're two miles apart wondering is going 30 miles per hour the other train is going 10 miles for how many minutes will it take before they meet each other?
if you put the frame of reference on one train, the trains then are approaching at 40mph.
time=distance/speed=10miles/40mph
= 1/4 hr or 15 min.
To determine how many minutes it will take for the trains to meet each other, we first need to find their closing speed. The closing speed is the sum of their speeds, as they move towards each other.
Given:
Train A's speed = 30 miles per hour
Train B's speed = 10 miles per hour
To find the closing speed:
Closing Speed = Speed of Train A + Speed of Train B
Closing Speed = 30 mph + 10 mph
Closing Speed = 40 mph
Now that we know the closing speed, we can calculate the time it takes for the trains to meet using the formula:
Time = Distance / Speed
The distance between the trains is given as 2 miles. Therefore:
Time = 2 miles / 40 mph
Converting the units to minutes:
1 mile = 1.60934 kilometers
40 mph = 64.37376 kilometers per hour
64.37376 km/h = 1.072896 km/min
Time = (2 miles * 1.60934 km/mile) / (1.072896 km/min)
Time = (3.21868 km) / (1.072896 km/min)
Time ≈ 3 minutes
So, it will take approximately 3 minutes for the two trains to meet each other.
