Two trains leave stations 560 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour
lana [24]

Answer: the two trains will meet in 2.8 hours

Step-by-step explanation:

Step 1

Speed of train A  = 90mph

Speed of train B = 110 mph

Since both trains  are travelling towards each other , their effective speed will be= 90 mph + 110mph= 200mph

Step 2

we know that Speed = distance / time

therefore Time = Distance / speed

Distance = 560 miles

Speed = 200 mph

Time = 560miles / 200mph

2.8 hours

Chris Christina collects stamps she is 47 stamps and all she has 20 from Europe the number of African stamps is 2 times the numb
AVprozaik [17]

Answer:

Step-by-step explanation:

Let x represent the number of stamps from Europe.

Let y represent the number of stamps from Africa.

Let z represent the number of stamps from Asia.

She has 47 stamps in all. This means that

x + y + z = 47 - - - - - - - - - - - 1

The number of African stamps is 2 times the number of Asian stamps. This means that

y = 2z

She has 20 stamps from Europe. Therefore, substituting x = 20 and y = 2z into equation 1, it becomes

20 + 2z + z = 47

3z = 47 - 20 = 27

z = 27/3 = 9

y = 2z = 2 × 9

y = 18

She has 20 stamps from Europe, 18 stamps from Africa and 9 stamps Asia.

Which equation gives the number of 1/3 inches that are in 5/6inch?
Annette [7]

Answer:

2\frac{1}{2}

Step-by-step explanation:

Let

x ----> the number of 1/3 in that are in 5/6 in

To find out the number of 1/3 in that are in 5/6 in, divide 5/6 by 1/3

so

x=\frac{5}{6}:\frac{1}{3}

Multiply in cross

x=\frac{15}{6}

Convert to mixed number

\frac{15}{6}=\frac{12}{6}+\frac{3}{6}=2\frac{3}{6}=2\frac{1}{2}
