Suppose you run 5 miles from your house to a friend's house at a speed of 6 miles per hour. When the time comes to return home, you are tired and walk the same 5 miles home at 3 miles per hour. How long did you spend running to your friend's house?

2hours and 30minutes

Step-by-step explanation:

6mph for 5 miles, would be 10 minutes per mile(in an hour because of 60). Only five were completed to itd take 50 minutes. 3mph for 5hours would take 1hr and 40 minutes because 3miles would take 1 hour which would make one mile take 20 minutes so you add the two twenties(for the last two miles) to get 40. Then u add them together. (50min+60min+40min)

i believe the answer is the polygon, heptagon.
