Nicholas Thompson begins a long-distance walk at a rate of 4 mph.
Forty-five minutes after he leaves, his wife, Kristin, realizes that Nicholas has forgotten his wallet.
Kristin gets on her bicycle and begins riding at a rate of 24 mph along the same path that Nicholas took.
-----
Nicholas DATA:
rate = 4 mph ; time = x hrs ; distance = 4x miles
------------------------
Kristin DATA:
rate = 24 mph ; time = x-(3/4) hrs ; distance = 24[x-(3/4)] miles
-------------------------------
Equation:
distance = distance
4x = 24x-18
20x = 18
x = 9/10 mile (distance at which Kristine will catch Nicholas)
