Go step by step to reduce the radical.

Here's one way to reduce the radical:

I factored 216 so that one of the factors (36) is a perfect square, and it's the largest such factor possible. Then I used the rule that to break up the radicand on the second step.

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.
