Private plane: 500km/h * 1h = 500km
Head-start.
d1 + d2 = 2100 km
500+500t + 700t = 2100
1200t = 2100-500 = 1600
t = 4/3 = 1 1/3 Hours(1:20 PM).
Using a chart:
At noon a private plane left Austin for Los Angeles,2100km away, flying at 500km/h. One hour later a jet left Los Angeles for Austin at 700km/h. At what time did they pass each other?
