The local train heading for westford at 60km/h and the express train heading for eastford at 80 km/h pass each other at centerville while heading in opposite directions along a straight roadbed. westford and eastford are 195 km apart, and if the local train makes one additional 15 minute stop after passing centerville the express completes its run before the local does. what is the maximum distance to the nearest kilometer between westford and centerville?

The maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.

Step-by-step explanation:

Local train stats:

Rate = 60 km/h

Distance = x km

Time = x/60 hours

Express train stats:

Rate = 80 km/h

Distance = km

Time = hours

Now we will equate both the times.

x = 83.57 km

km

Hence, the maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
