Question 217830
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/(1/2)}}}, or {{{4/.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:


{{{6/8}}} = {{{highlight_green(.75)}}} of an hour, or {{{highlight_green(45)}}} minutes.
