17 hours

Step-by-step explanation:

Rachel has already written 10pages, and she expects to write 1page for every additional hour spent writing. How many hours will Rachel have to spend writing this week in order to have written a total of 27pages?

The illustration can be modelled using the equation

y = 10 + 1(x)

y = 10 + x

Where,

y = total number of pages

x = number of hours

10 = pages already written

If y = 27 pages, find x

y = 10 + x

27 = 10 + x

27 - 10 = x

17 = x

x = 17 hours

Rachel have to spend 17 hours writing this week in order to have written a total of 27pages

54 kilometers per hour

step-by-step explanation:

according to rules:

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.
