Expand $\left(x^2 \frac{1}{x}\right)^3$. (write the terms with higher degree first, so for example an $x^2$ term would come before $x$ or $\frac{1}{x}$.)

Step-by-step explanation:

We can use the pascal triangle to find the coefficients of the expasion of the cube. It holds that

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.
