Two trains are moving towards each other. One train moves at a speed of 50 mph, and the other train travels at 60 mph. How soon will they meet, if originally the distance between them was 340 miles?

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.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

about 0.75 hours
