Answer: 7 hr

Step-by-step explanation:

Given

Distance between Emily and Kylie is $140\ \text{miles}$

Speed of Emily $v_e=12\ mph$

Speed of Kylie $v_k=8\ mph$

Distance traveled by Emily $\Rightarrow d_e=12t$

Distance traveled by Kylie $\Rightarrow d_k=8t$

$\Rightarrow 12t+8t=140\\\Rightarrow 20t=140\\\Rightarrow t=7\ hr$

They will meet after 7 hour.
