True
Step-by-step explanation:
If A/B and C/D are rational expression then
A/B*C/D

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 <===
Answer:
216 times smaller, 21600%, the cross section is a rectangle or square
