You would need to distribute the 8 inside the parenthesis to get x+80x+200 then combine like terms to get 81x+200
I'm pretty sure the answer is 54! hope this helps
The answer is 6.66666666~
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.
