Is -23 greater, less or equal than 23?

-23 is less than 23.

Well, right from the start we know that -23 isn't greater than +23 for obvious reasons. -23 is less than +23 for even more obvious reasons. But when you think about it, -23 and +23 could be equal to each other. The reason for this is because the absolute value of -23 is +23.

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.
