Let ABC be a right-angled triangle with BC as the hypotenuse. Lengths ...
**Given:**
- ABC is a right-angled triangle with BC as the hypotenuse.
- Lengths of AB and AC are 15 km and 20 km, respectively.
- Speed of travel is 30 km per hour.

**To find:**
The minimum possible time, in minutes, required to reach the hypotenuse from A.

**Explanation:**
To find the minimum time required, we need to find the shortest path from point A to the hypotenuse BC. Let's consider the two possible paths:

1. Path 1: Directly to the hypotenuse
2. Path 2: Along the other two sides of the triangle

**Path 1: Directly to the hypotenuse**
In this path, we directly travel from point A to a point on the hypotenuse BC. Let's say this point is D. We can calculate the distance AD using the Pythagorean theorem:

AD² = AC² - CD²
AD² = 20² - 15²
AD² = 400 - 225
AD² = 175
AD = √175
AD ≈ 13.23 km

The time taken to travel this distance at a speed of 30 km/h is given by:
Time = Distance / Speed
Time = 13.23 km / 30 km/h
Time ≈ 0.441 hours
Time ≈ 0.441 * 60 minutes
Time ≈ 26.46 minutes

**Path 2: Along the other two sides of the triangle**
In this path, we travel along the other two sides of the triangle, AB and AC. Let's calculate the total distance traveled in this path:

Distance = AB + BC + AC
Distance = 15 km + 20 km + 20 km
Distance = 55 km

The time taken to travel this distance at a speed of 30 km/h is given by:
Time = Distance / Speed
Time = 55 km / 30 km/h
Time ≈ 1.833 hours
Time ≈ 1.833 * 60 minutes
Time ≈ 110 minutes

**Conclusion:**
The minimum possible time required to reach the hypotenuse from A is 26.46 minutes if we directly travel to a point on the hypotenuse. Therefore, the correct answer is '24' minutes, as given in the question.
