If the distance to Grandmother’s house is 8 km and you walk at a steady speed of 4 km/h, how long will it take to reach the house, including a 15‑minute break? Express the answer in hours and minutes.

Step-by-step solution

1. Compute walking time: $8\text{km}÷4\text{km/h}=2\text{hours}$.
2. Add the 15‑minute break: $2\text{hours}+15\text{minutes}=2\text{hours}15\text{minutes}$.
3. State the final time.
