L.C. Maths H.L. 2025 Q8 (c) & (d): Distance Speed Time & Pythagoras Method

Описание: 🔥 Leaving Cert Maths H.L.: Distance Speed Time - Combining Formulas for Full Marks 🔥

This video gives you the full solution for *Question 8 (c) & (d)* from the **LCHL 2025 Paper 1**.

This multi-part problem requires two different calculations for two different routes:

*Part (c): Kayak & Run Route:* We use the simple *Time = Distance / Speed* formula to calculate the total time taken for the route via Point A. We check the units to ensure the final time is correct in hours.

*Part (d): Direct Kayak Route:* This is the challenging part! We first use the *Pythagoras Theorem* from page 16 of your tables to find the straight-line distance (S to F). We then use the *Time = Distance / Speed* formula and a crucial unit conversion to find the time correct to the nearest minute.

Mastering this video proves you can apply formulas across different syllabus sections!
