You go for a half day hike. in 4 hours, you hike 10 miles. which is a unit rate that describes your journey? a- 5 miles per hour b- 2.5 miles per hour c- 4/10 (< --fraction) miles per hour d- 10 miles per hour < mum thinks this is 'answer' > ,<

B is reasonable

Step-by-step explanation: In 4 hours, you hike 10 miles. Divide 10 miles by 4 hours to get miles per hour, which is what you want to solve for in this problem. 10 divided by 4 is 2.5, which means you can hike 1 mile in 2.5 hours.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
