<PRE><B>Question 221565</B>
A bus leaves a depot traveling at 40 mi/hr.. An hour later a car leaves the station at 60 m/hr. Sketch d=fn(t) diagram When (t) and where (d) do they meet?
------------------
Bus DATA:
rate = 40 mph ; time = t hrs. ; distance = 40t miles
-----------------------
Car DATA:
rate = 60 mph ; time = (t-1) hrs; distance = 60(t-1) miles
-------------------------
Equations:
Bus:::: d = 40t
Car;;;; d = 60(t-1)
--------------------------
{{{graph(400,300,-10,10,-10,150,40x,60(x-1))}}}
-----------------------------
They meet at t = 3 hrs. and d = 120 miles
