The question is not specified but probably needs the time Quinn spent exercising. That time is 3 hours and she arrived home at 1pm.
First find the time Quinn spent during the first stage of the exercise. She ran for 3 miles at 6 miles per hour so the time taken was:
<em>Time = Distance / speed</em>
= 3 / 6
= 0.5 hours
She then rested for 1 hour bringing the total to:
= 0.5 + 1
= 1.5 hours
She then walked home at 2 miles per hour. Remember that her home is 3 miles away so the time she took in the last stage is:
<em>= Distance / time</em>
= 3 miles / 2 miles per hour
= 1.5 hours
The total time she took including this last stage is:
= 1.5 + 1.5
= 3 hours
She would have arrived back home at:
= 10 am + 3 hours
= 1 pm
In conclusion, she took 3 hours and arrived at 1 pm for this run.
