Answer:
No this does not sound reasonable because this distance seems to be an over-exaggeration
Step-by-step explanation:
She would have to walk at a speed of 14 miles per hour to reach 7 miles in 30 minutes and it is impossible to run (not walk because that speed is not called walking anymore) consistently at 14 miles an hour for 30 minutes. So 7 miles is an over-exaggeration.
