Step-by-step explanation:
Given
The attached graph
Required
Determine the solution
The solution here is the intersection points of the two lines. From the attachment, both lines meet


<em>Hence, the solution is: </em>
<em></em>
Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30
speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===
