Brent and Lance leave a park on bicycles traveling at constant rates in opposite directions. After 2.5 hours, they are 85 miles apart. If Lance bikes 2 mph faster then Brent, how fast is Lance biking?

Just maybe u can use the fact that speed = distance/time. I would suggest distance covered my lance = 85/2, maybe? After 2,5 hours since both are travelling at same constant speed, Lances speed = 85/2)/2,5 +2?
