Create equations to represent a relationship between quantities.
Define appropriate quantities for descriptive modeling.
Two trains leave a station heading in opposite directions. The first train travels at two-thirds the rate of the second train. If the trains are 360 miles apart after three hours, then at what rate (in mph) was each train traveling?

We given:
Distance =360 miles
time=3 hours
het spped of second train =xmph
speed of first train =2x3mph when move in opposite direction
Relative speed =x+2x3
Distance =speed × time
360=5xcancel 3×cancel 3
x=72mph
Speed of first train =23x
=23×72
=78mph
Dpeed of second train =x
=72 mph
