Distance between 2 electric poles is 60 metre. A passenger counts the electric poles how many poles he will counts in 3 hours if speed of train is 60 km/hr.

Options

A. 3011
B. 3021
C. 3001
D. 3701

Answer

To solve the problem step by step, we will follow these calculations:

### Step 1: Calculate the distance traveled by the train in 3 hours.
- **Formula**: Distance = Speed × Time
- Given:
- Speed of the train = 60 km/hr
- Time = 3 hours
- Calculation:
\[ \text{Distance} = 60 \, \text{km/hr} \times 3 \, \text{hr} = 180 \, \text{km} \]

### Step 2: Convert the distance from kilometers to meters.
- **Conversion factor**: 1 km = 1000 meters
- Calculation:
\[ 180 \, \text{km} = 180 \times 1000 \, \text{meters} = 180000 \, \text{meters} \]

### Step 3: Determine how many poles are there in the total distance.
- **Distance between two poles**: 60 meters
- To find the number of poles, we divide the total distance by the distance between the poles.
- Calculation:
\[ \text{Number of poles} = \frac{180000 \, \text{meters}}{60 \, \text{meters}} = 3000 \]

### Step 4: Include the first pole that the passenger starts counting from.
- Since the passenger counts the first pole at the starting point, we add 1 to the total number of poles counted.
- Calculation:
\[ \text{Total poles counted} = 3000 + 1 = 3001 \]

### Final Answer:
The passenger will count **3001 electric poles** in 3 hours.
