A rectangle has a length x centimeters and a width that is equal to half its length. The perimeter of the rectangle is 50 centimetres. What is the length and width of the rectangle? no links just answer the question with a clear explanation and I'll give you

Step-by-step explanation:

Let x = length

Then width = (1/2)x

Perimeter = 2(length) + 2(width) = 54

                  length + width = 27

So, x + (1/2)x = 27

           (3/2)x = 27

                 x = 27(2/3) = 18     (1/2)x = 9

 length = 18 cm and width = 9 cm

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
