Answer: None of those are functions
Step-by-step explanation: They all fail the vertical line test. x values do not repeat. Those intersect more than one pint on the relationship if you were to take a line and move it across the graph.
Answer:
3.0909 hours
Approximately ≈ 3.1 hours
Step-by-step explanation:
We are given the following values or variables in the question above
Train A moves at a speed of = 50mph( miles per hour)
Train B moves at a speed of = 60mph( miles per hour)
The original distance between them = 340 miles
We are asked to determine how soon they will meet, which means we are to determine the time(in hours) at which they would meet.
The formula to be used to calculate the time in hours =
Time(hours) = Distance(miles) ÷ Relative(Total) Speed (mph i.e miles per hour)
Distance = 340miles
Relative or Total Speed = Speed of Train A + Speed of Train B
Speed = 50mph + 60mph
Speed = 110mph(miles per hour)
Time (hours) = 340miles ÷ 110mph
Time in hour = 3.0909 hours
Approximately ≈ 3.1hours
Therefore Train A and Train B will meet in 3.1 hours.
