<PRE><B>Question 1189377</B>
 Antony leaves Kingstown at 2:00 P.M. and drives to Queensville, 256 km distant, at 72 km/h.
 At 2:15 P.M. Helen leaves Queensville and drives to Kingstown at 64 km/h.
 At what time do they pass each other on the road?
:
When they pass each other, the sum of their distances will be 256 km
15 min = .25 hr
let t = the travel time of Antony when they meet
then
(t-.25) = the travel time of Helen
;
72t + 64(t-.25) = 256
72t + 64t - 16 = 256
136t = 256 + 16
136t = 272
t = 272/136
t = 2 hrs is Antony travel time from 2 PM
They should meet at 4 PM
:
:
Find the actual dist each traveled and check their sum.
1.75 * 64 = 112 km
2 * 72  = 144
-----------------
total dist: 256 km</PRE>
