It will take 2.2 hours for the trains to meet.
Step-by-step explanation:
Given,
Distance between two trains = 396 miles
Speed of one train = 95 mph
Speed of other train = 85 mph
Combined speed of trains = 95+85 = 180 mph
Distance = Speed * Time
Time = 
Time = 
Time = 2.2 hours
It will take 2.2 hours for the trains to meet.

Answer:
Circumference = PI * diameter
Circumference = 3.14159 * 14
Circumference = 43.98226 inches
Area = PI * radius^2
Area = PI * 7^2
Area = PI * 49
Area = 153.9380400259 square inches
