Is that the entire question. If you're looking to find the unit price (how much you are being charged for on unit) you can divide 300 by 19 and you get 15.79, which I rounded to the nearest tenth
The sign would be NEGATIVE
Answer:
The passenger train traveled at a speed of 25 miles/hour
Step-by-step explanation:
In this question, we are asked to calculate the rate at which a particular passenger train is traveling.
We use the information in the question to answer as follows;
Firstly, we identify that they traveled at the same time but their distances are different. This means that their speed must be different also.
Mathematically, we know that time can be calculated as distance/ time.
Let us say the speed at which the passenger train traveled is x miles per hour. This means that the speed of the freight train which was 5 miles per hour slower would be (x-5) miles per hour.
We know their times are equal;
Hence;
100/x = 80/(x-5)
We cross multiply
100(x-5) = 80x
100x -500 = 80x
100x-80x = 500
20x = 500
x = 500/20
x = 25 miles per hour
I am assuming 5/3 refers to 5/3rds of a full revolution.
radians is easier for now so I'll do that first. on full revolution = 2π radians, but you have 1 and 2/3rds revolutions, so that is 2π+2π*(2/3)=10π/3 radian turn
to convert from radians to degrees multiply the radians by 180/π, so (10π/3)*(180/π) => 600degrees
Final answer:
5/3 turn is 600 degrees and 10π/3 radians
Hope I helped :)
