Question

Answer 1

Answer:

a) Destiny can run 1 mile is 6 minutes.

b) Destiny can walk back 1 mile is 16 minutes.

Step-by-step explanation:

The running rate of Destiny is

$(\frac{1}{8}) \textrm{mile in} (\frac{3}{4}) \textrm{minutes}$

So, she runs 1 mile in $8 \times (\frac{3}{4} )\textrm{minutes}$  

= 6 minutes

Hence, Destiny can run 1 mile is 6 minutes.

The walking rate of Destiny is

$(\frac{1}{4}) \textrm{mile in} 4  \textrm{minutes}$

So, she walks 1 mile in $4 \times (4 )\textrm{minutes}$  

= 16 minutes

Hence, Destiny can walk back 1 mile is 16 minutes.
