D=RT DISTANCE=RATE*TIME
200=(300-30)T
200=270T
270T=200
T=200/270
T=.74NHOURS TO GO FROM NYC TO SF.
200=(300+30)T
200=330T
330T=200
T=200/330
T=.6 HOURS FOR THE RETURN TRIP.
---------------------------------------------------------------
IF THE DISTANCE IS SUPPOSED TO BE 2000 MILES FROM NYC TO SAN FRANCISCO.
JUST MULTIPLY THE ANSWERS OF .74 BY 10=7.4 HOURS & THE RETURN TRIP TAKES .6*10=6 HOURS.
