Step-by-step explanation:

We need to know that rational numbers are numbers that can eb written as a ratio of two integers.

Given

S =

Add

Since √4 = 2 and √9 = 3

Since S+M is written as a ratio of two integers, hence the value of S and M for which S+M are rational is respectively

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.
