The cattle train
speed - 36.5 km/h
time - x h
the passenger train
speed - 29.2 km/h
time - (2.4+x) h
The cattle train caught up to the passenger train so the distance they travelled is the same.
Distance is speed times time.
The passenger train travelled for 12 hours before the cattle train caught up.
speed - 36.5 km/h
time - x h
the passenger train
speed - 29.2 km/h
time - (2.4+x) h
The cattle train caught up to the passenger train so the distance they travelled is the same.
Distance is speed times time.
The passenger train travelled for 12 hours before the cattle train caught up.
To find the number of solutions of a system of linear equations you need to identify the slope (m) in each equation:
-If the slope is the same in both lines the system has no solution
-If the slope is different in the lines the system has one solution
-If the equation are the same (incluided the value of b) the system has infinitely many solutions
You have the next equations:
Write the equations in slope-intercept form y=mx+b (solve for y).
First equation:
Second equation:
