Answer:
BC is 10 units.
Step-by-step explanation:
Given that, ![\frac{AB}{BC}=\frac{AE}{ED}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BBC%7D%3D%5Cfrac%7BAE%7D%7BED%7D)
AB=12 units
AD=33 units
AE=18 units
From the figure, AD=AE+ED ⇒ 33=18+ED ⇒ ED=15 units
![\frac{AB}{BC}=\frac{AE}{ED}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BBC%7D%3D%5Cfrac%7BAE%7D%7BED%7D)
⇒ ![\frac{12}{BC}=\frac{18}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7BBC%7D%3D%5Cfrac%7B18%7D%7B15%7D)
⇒ ![BC=\frac{12\times 15}{18}=10 units](https://tex.z-dn.net/?f=BC%3D%5Cfrac%7B12%5Ctimes%2015%7D%7B18%7D%3D10%20units)
Hence, BC is 10 units.

Answer:
240kmh
Step-by-step explanation:
The distance that the train traveled in 30s is the difference of the total length of the tunnel and the train (2000m). This means it travels 2000m/30s. This ratio is the same as 240000/3600s or 240km/1hr.
