Answer 1

Awww man I read the question and I was like I know it because I did it in my head and was typing the answer and saw someone already typed a answer before me anyways it’s 12 miles per hour

Answer 2

This is a fraction equal to

30 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

30 miles ÷ 2.5

2.5 hours ÷ 2.5

=

12 miles

1 hour = 12 miles hour = 12 miles per hour
