Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 kilometres per hour and the other travels at an average speed of 70 kilometres per hour. How long after they leave the station will they be 50 km apart?

Answers

Answer:

1/3 hr or 20 min.

Step-by-step explanation:

Call the trains A and B

Remember d = rt

Distance train A travels is 80t

Distance train B travels is 70t

Now, 80t + 70t = 50

              150t = 50

                    t = 50/150 = 1/3 hr or 20 min.

Answer: 20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time.

Step-by-step explanation:

Answers

Answer:

C

Step-by-step explanation:

Remark

The easiest way to do this is to add the two givens together and then multiply by two. Why 2?  Because the formula is P = 2(L + W)

Givens

L = 8x - 2

W = 4x - 4

Solution

P = 2*(8x - 2 + 4x - 4)

P = 2*(12x - 6)

P = 24x - 12

Answer:

1.The formula to convert Celsius to Fahrenheit is:

F = 1.8 C + 32

Multiply the Celsius temperature by 1.8.

Add 32 to this number.

Report the answer in degrees Fahrenheit.

Example: Convert 20°C to Fahrenheit.

F = 1.8 C + 32

F = 1.8 (20) + 32

1.8 x 20 = 36 so F = 36 + 32

36 + 32 = 68 so F = 68°F

20°C = 68°F

Identify the points which of the following coordinate pairs make the equation x - 9y = 12 true?

Show your reasoning.

1. ( 12, 0 )

2. ( 0, 12 )

3. ( 3, -1 )

4. ( 0, - 4/3 )

Answers

Answer:

Step-by-step explanation:

Because in equation x-9y=12

If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12

So, (12,0) make equation

(3,-1) also make equation

(3)-9(-1)=12

(0,-4/3) also make equation

Because

0-9(-4/3)=12

Only (0,12) is not making

Beacuse

(0)-9(12) is not equal to 12
