H) 4.25 mi
Work Step by Step
In the first part of the problem, you must plug in 30 min into 5.5 mi/h. Since 30 minutes is half an hour, you use $0.5 h$. $5.5\times0.5$ $5.5\div2$ $2.75$ For the second part, you insert 15 min into 6 mi/h. As 15 minutes is a quarter of an hour, use $0.25 h$. $6\times0.25$ $6\div4$ $1.5$ For the final answer, add up the two previous solutions, $2.75$ and $1.5$. $2.75+1.5$ $4.25$ The final answer is 4.25 miles.
