What is the answer to the question?

360g plain flour

3 eggs

900ml milk

Step-by-step explanation:

To make 4 pancakes you would do 240g÷2=120g

2 eggs÷2=1

600ml÷2=300ml

all this makes a total of 4 pancakes.

to make 12 pancakes you do 4×3 soo..

120g×3=360g

1×3=3

300ml×3=900ml

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
