Express Cruise Ship has 1,000 cabins. There are 200 first class cabins available and the rest are standard cabins. Use f as the number of first class cabins sold and as the number of standard cabins sold for the next cruise. Which of the following would represent this situation? A. f + c <= 1, 000f <= 200c <= 800
B. f f + c <= 1, 000f <= 200c <= 200;
C. f + c >= 1, 000f >= 200c >= 200;
D. f + c >= 1, 000f >= 200c >= 800

answer: x

step-by-step explanation:

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.

i think the correct option is the second option.
