1/12

Step-by-step explanation:

1/3 - 1/4 can't be subtracted, so you have to find the least common multiple between 3 and 4, which is 12. When you change the denominators to 12, you have to multiply the numerator by the number needed to multiply with the denominator to make 12. So 1/3 would become 4/12, because 3 x 4 is 12 and 1/4 would become 3/12, because 4 x 3 is 12.

4/12 - 3/12 = 1/12

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.
