i need help

60

Step-by-step explanation:

LCM = least common multiple, the smallest product all the numbers have in common.

Let's find the multiples of the numbers:

5: 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60

6: 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72

12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120

We can see that the smallest multiple all these numbers have in common is 60.

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.
