Answer 2

Problem Analysis

We have two villages, and a cyclist and a motorcyclist start simultaneously from each village and meet after 4 hours. The cyclist's speed is 15 km/h, and the motorcyclist's speed is 57 km/h. We need to find the distance between the villages.

Solution

To find the distance between the villages, we can use the formula:

Distance = Speed × Time

Let's calculate the distance using this formula.

Calculation

The cyclist's speed is 15 km/h, and the time is 4 hours. Therefore, the distance traveled by the cyclist is:

Distance_cyclist = Speed_cyclist × Time = 15 km/h × 4 h = 60 km Similarly, the motorcyclist's speed is 57 km/h, and the time is 4 hours. Therefore, the distance traveled by the motorcyclist is:

Distance_motorcyclist = Speed_motorcyclist × Time = 57 km/h × 4 h = 228 km Since the cyclist and the motorcyclist meet after 4 hours, the total distance between the villages is the sum of the distances traveled by both:

Total_distance = Distance_cyclist + Distance_motorcyclist = 60 km + 228 km = 288 km

Therefore, the distance between the villages is 288 km.

Answer

The distance between the two villages is 288 km.
