Kelly is knitting a scarf for her brother. It took her 1/3 hour to knit 3/8 foot of the scarf. How fast is Kelly's knitting speed, in feet per hour?

1 1/8 feet    or 9/8 feet

Step-by-step explanation:

Kelly's knitting speed is 1 foot 1.5 inches per hour.

Step-by-step explanation:

1. Convert the fractions to decimals/numbers: 1/3 hour = 15 minutes. 3/8 of 12 is 4.5.

2. Multiply these numbers to make 1 hours worth. Remember to always multiply both numbers by the same number.

15x3=60

4.5x3=13.5

13.5= 1 foot 1.5 inches.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
