A Metra commuter train leaves

Union Station in Chicago at 12 noon. Two hours later, an

Amtrak train leaves on the same track, traveling at an

average speed that is 50 miles per hour faster than the

Metra train. At 3 PM the Amtrak train is 10 miles behind the

commuter train. How fast is each going?

Consider the figure below:

Given: $v_A = v_M + 50$

And from the figure:

$3v_M = v_A + 10$

Answers:

$v_A = 80 ~ \text{mph}$

sir anong gamit mo paggawa ng figure?
