Train “a” leaves westtown and travels at 50 mph toward smithville, 330 miles away. at the same time, train “b” leaves smithville and travels at 60 mph. after how many hours do the two trains meet?

train A travels at 50 mph

train B travels at 60 mph

60 +50 = 110

330/110 = 3

they will meet in 3 hours

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
