The second question is written in Sinhala, and here's a rough translation:

Question 2:
The distance between points $X$ and $Y$ is 420 km. Point $X$ is located at a distance of 100 km from a city $C$, while point $Y$ is 60 km from city $C$. A bus traveling from city $C$ reaches point $X$ at 7:00 AM. If the bus travels at a speed of 60 km/h, at what time will the bus reach point $Y$?

Let me solve this:

Given:

• Distance from $X$ to $Y$ = 420 km
• Bus speed = 60 km/h
• Time at $X$ = 7:00 AM

The total time it will take to travel from $X$ to $Y$: $\text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{420}{60} = 7 \, \text{hours}$

So, if the bus leaves $X$ at 7:00 AM, after 7 hours it will reach $Y$, which is at: $7:00 \, \text{AM} + 7 \, \text{hours} = 2:00 \, \text{PM}$

Final Answer:

The bus will reach point $Y$ at 2:00 PM.

Would you like more details or have any questions on this? Here are five related questions for further exploration:

1. What if the bus stopped for a 30-minute break? What time would it reach $Y$?
2. How would the arrival time change if the speed of the bus was 80 km/h?
3. If the bus departed $X$ at 6:00 AM instead of 7:00 AM, what would be the new arrival time?
4. What would happen if the road between $X$ and $Y$ had different speed limits?
5. How far would the bus travel if it had to make detours along the route from $X$ to $Y$?

Tip: When solving time and distance problems, always ensure that the units (km, hours, minutes) match up to avoid calculation mistakes.
