Answer:
10 hours or 2 hours
Step-by-step explanation:
Condition 1 - Both the trains are moving the a same direction.
- Time = distance÷(speed of A - speed of B)
- Time = 500÷(150-100) = 10 hrs
- It will take 10 hrs for them to meet and they will meet exactly at 150×10 = 1500 km from Point A
Condition 2 - Both the trains are moving in opposite directions.
- Time = distance÷ (speed of A + speed of B)
- Time = 500÷(150+100) = 2 hrs
- It will take 2 hrs for them to meet and they will meet exactly at 150×2 = 300 km from Point B
The molecules in the sugar dissolved in water. it did not dissociate though, just dissolved. the atoms in each individual molecule stayed in tact, but the intermolecular forces broke apart.
The first option is correct because it is base x height for rectangles and every triangle is half of a rectangle
