let d be the distance you travel. So 12-d is the distance friend travels. You both pedal for time t (hrs)

d=4t

12-d=11t

add the equations. 12=15t t=12/15 hr

then find d, and 12-d from either equation.

speed toward each other = 11+4 = 15 mph

so time = 12/15 = 4/5 hour = 48 minutes

4/5 * 4 = 16/5 = 3.2 miles

4/5* 11 = 44/5 = 8.8 miles

Now you should be able to do it with a different speed.
