(3x – 4y)^2
9x^2 – 24xy + 16y^2
(3x + 2)(9x2 - 6x + 4)
27x^3 - 8
9x2 + 3x– 20
(3x+ 5)(3x - 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.
