You and your friend live 12 miles apart. You leave home at the same time and travel toward each other. You walk at a rate of 4 mph your friend rides a bike at 11 mph.
A. How long after you leave will you meet?
B. suppose your friend travels at a rate of 12 mph how much sooner will you meet? How far from home will each of you be?


A.

We will meet: highlight_green%284%2F5%29 hour, or highlight_green%2848%29 minutes after leaving our respective destinations

B.

With friend traveling at 12 mph, the meeting will take 3%2F4%29 hour or 45 minutes. 

Therefore, we will meet highlight_green%283%29 (48 - 45) minutes earlier

C.

With friend traveling at 12 mph, we will meet highlight_green%283%29 miles from my home, which is

highlight_green%289%29 miles from the friend's home.

You can do the check!!
