Two trains leave Sacramemto at the same time. One travel East at 40mph. The other traveled West at 60mph.Write amd solve a system of linear equations that can be used to determine when the trains are 280 miles apart.
Thank You!!!

Two trains leave Sacramemto at the same time. One travel East at 40mph.
The other traveled West at 60mph.
Write amd solve a system of linear equations that can be used to determine when the trains are 280 miles apart.
:
Let t = travel time required for them to be 280 mi apart
:
write a distance equation; dist = speed * time
:
train 1 dist + train 2 dist = 280 mi
40t + 60t = 280
100t = 280
t = 280/100
t = 2.8 hrs, they will be 280 mi apart
:
:
Check this by finding the distance that each traveled
2.8*40 = 112 mi
2.8*60 = 168
----------------
total: 280 mi
