I will tell you how I got all of these answers. For the first one is just plug in the number in is /of = percent / 100.

It would look like X/30=75/100.  

Then you would cross multiply 30 x 75 to get 2,250.

Then you would divide that by 100 to get 22.5. I just rounded down.

Then you would do the same for the next one just replace the 75 with 90.

For the last question what I did was take the answer from B and replace the 30 and replace the 90 with the 55. And follow the same steps. I hope that this helps you.

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.
