your friends house is 2 miles away from yours. You bike for 1/2 hour from you friends house in the opposite direction and end up 6 miles from home. about how long will it take to get home if you take the same route

Since you're 2 miles from home, and since you bike for 1/2 hour, from your friend's house in the opposite direction and end up 6 miles from home, you would have traveled 4 miles from your friend's house.

Speed from your friend's house, in the opposite direction is 8 mph 4%2F%281%2F2%29, or 4%2F.5

Since you're 6 miles from home, your average rate of speed will be the same 8 mph, then time to get home would be:

6%2F8 = highlight_green%28.75%29 of an hour, or highlight_green%2845%29 minutes.
