Without making a graph of an absolute value function, you can describe its position on a graph

Yeah!! In absolute value, you have to darken all the way to the negative of that value in addition of its real value

Suppose, you have to describe absolute value of 3 on a graph, then you have to mark the line from -3 to 3

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.
