Answer:

20 minutes

Step-by-step explanation:

Method 1:

(0.75)/(0.25)=(1)/(x)

0.75*1.333333=1, so multiply 0.25 by 1.333333 to find the value of x!

0.25*1.333333=0.33333, or one-third of an hour, or 20 minutes.

Method 2:

(0.75)/(0.25)=(1)/(x)

Cross-multiply

0.75x=0.25

(0.25)/(0.75)=x

x=0.33333 hours

Emily will use 20 minutes or 1/3 hour to walk 1 mile.

Note that 3/4 = 0.75

1/4 hour = 1/4 × 60 = 15 minutes

Let the amount of time that it takes Emily to walk 1 mile be represented by x.

Therefore, the equation to solve the question will be:

0.75 /1 = 15/x

Cross multiply

(0.75 × x) = (1 × 15)

0.75x = 15

x = 15/0.75

x = 20

Therefore, Emily will use 20 minutes or 1/3 hour to walk 1 mile.
