Answer:
1.9125 seconds
Step-by-step explanation:
The units give you a clue as to the math needed.
(12.75 mi)×(0.15 s/mi) = (12.75×0.15) s = 1.9125 s
It would take 1.9125 seconds to go 12.75 miles.

<em>Additional comment</em>
You notice that miles are in the numerator of the distance, and the denominator of the given rate. That means those units will cancel when the numbers are multiplied. The remaining units will be seconds, the unit in the numerator of the given rate. That is what the problem is asking for.
Answer:
x = 1/7
Step-by-step explanation:
23x - 15x = x-1
8x = x - 1
8x - x = 1
7x = 1
x = 1/7
Answer:
the smallest part is 2
Step-by-step explanation:
lets take x as the smallest part
then the largest part=3x
the middle sized part=2x
x+2x+3x=12
6x=12
x=12/6
x=2
therefore the smallest part is equal to 2
