Find the unit rate. I honestly just want an explanation on how to find it.

Answer:
.5 miles per 1hr
Step-by-step explanation:
the unit rate is distance per 1 hr. your goal is to change 3/4 hr to 1 hr. how do you do this? you multiply the inverse of 3/4 (4/3) by both sides. ex
3/8mile per 3/4hr
×4/3
.5 mile per 1 hr
