115 miles in 2 hours is what we call a rate: a comparison of two numbers with very different units. This rate is 115 miles / 2 hours. It's almost like a fraction! The numerator is 115 miles, and the denominator is 2 hours.

<span>So, what is a unit rate? A unit rate is a rate (comparison of two numbers) with a denominator of 1. So we need our rate, 115 miles / 2 hours, to have a denominator of 1. We need to make the bottom number of our rate 1 hour. How do we do that? Well, we need to divide both the numerator (115 miles) and the denominator (2 hours) by 2!
</span>
115/2=57.5. 2/2=1. So, this rate is equal to 57.5 miles / 1 hour. Since the denominator is 1, THAT's a unit rate!!

Answer: 57.5 miles / 1 hour
