Im hella confused please help haha

Step-by-step explanation:

1, 4, and 9 are square numbers.

2, 4, 6, 8, 10, and 12 are even numbers.

4 is both a square number and an even number, so it goes in the intersection.

1 and 9 are square numbers, but not even, so they go in the S circle.

2, 6, 8, 10, and 12 are even numbers, but not squares, so they go in the E circle.

The other numbers (3, 5, 7, and 11) go in the lower left hand corner.

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.
