Answer:
8 miles
Explanation:
We know the student can run 6 miles in 3/4 hour (hr). Let's make that into a speed (rate, miles/hour) and assume the student can maintain that same opace for an hour.
(6 miles)/(3/4 hr) = 6*(4/3) miles/hr
6*(4/3) miles/hr = (6/3)*4 or 2*4 miles/hr
The student's speed is 8 mile/hr.
This means he/she will travel (8 mile/hr)*(1 hr) = 8 miles in 1 hour.
