So i just started modeling and two step inequalities and my question is 62°f and it drops 2 degrees every hour .how many hours was it before the temperature was below 40°

It was 11 hours because if the temperature drops 2 degrees after every hour, after 11 hours, the temperature would have dropped 22 degrees and 62 - 22 = 40.

11 hours

Equation:

62 - 2x = T

62 - 2(11) = 40

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

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.
