Three vertices of a rectangle have coordinates (–3, 1), (7,1), and (7, –4). what are the coordinates of the fourth vertex of the rectangle? a. (–3, –4) b. (–3, –1) c. (7, –3) d. (7, 4)

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.
