Answer:
His friend lives 7.29 miles away
Step-by-step explanation:
All you have to do is times 0.27 by 27 and you get 7.29
Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
There's no way to do that without seeing the drawing or hearing a lot more information. For one thing, we don't even know the size of the circle yet.
Are you solving for X? If so, your answer will be x=-3. Hope this helps!
