Evelyn walks on a treadmill for at least 1 hour but not more than 2 hours. She walks at an average rate of 3.5 miles per hour. The distance Evelyn walks in t hours is represented by a function. r(t)=3.5t

What is the practical domain of the function?

all multiples of 3.5 between 3.5 and 7, inclusive
all real numbers
all real numbers from 1 to 2, inclusive
all integers from 1 to 2, inclusive

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

r = 78539458390583095803458309458039485093485 or just 3
