Which property is shown x = y and y = z so x=z a: transitive property b: commutative property of multiplication c: multiplicative identity d: reflexive property

Transitive property

Step-by-step explanation:

If x is equal to y and y is equal to z than x is equal to z because x was equal to y and y was equal to z that means that x and z are the same value because they were both equal to y.

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.
