f=4x-148

62 degrees fahrenheit

Step-by-step explanation:

Chirps per minute=148

x=148

x=4f-148

100=4f-148

248=4f

62=f

If snowy tree crickets chirp at 100 chirps per minute, the temperature outside is 62 degrees fahrenheit.

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.
