What is 0.45 divide by 0.3 please show work.

Step-by-step explanation:

We can use standard form to make it simpler to deal with.

0.45=45×10^-2

0.3=3×10^-1

Now 45÷3=15

10^-2÷10^-1=10^-1

So the answer is 15×10^-1 OR 1.5

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.
