Which equations for the measures of the unknown angles x and y are correct? Check all that apply. ○x=cos-1[a/c] ○x=sin-1[c/b] ○x=tan-1[c/a] ○y=sin-1[a/c] ○y=cos-1[c/b]​

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.
