Vera_Pavlovna [14]

<h2> Miranda's rate is 12 hours per mies.</h2>

Step-by-step explanation:

Given by question,

Miranda began her ride from home merely that she was 50 miles away from home after 4 hours of riding.

To find, Miranda's rate = ?

2 hours later she was 974 miles from home.

∴ 2 hours she rode = 74 miles - 50 miles

Miranda rides 24 miles in 2 hours.

∴ Miranda rides in 1 hour = $\dfrac{24}{2}$ $\dfrac{miles}{hour}$

= $12$ $\dfrac{miles}{hour}$

Thus, Miranda's rate is 12 hours per mies.
