In a race, Ravi covers 5 km in 20 min. How much distance will he cover in 100 min ?

Options

A. 40 km
B. 35km
C. 26km
D. 25km

Answer

To solve the problem step by step, we will use the concept of the unitary method.

**Step 1: Find the distance covered by Ravi in 1 minute.**
- Ravi covers 5 km in 20 minutes.
- To find the distance covered in 1 minute, we divide the total distance by the total time.

\[ \text{Distance in 1 minute} = \frac{5 \text{ km}}{20 \text{ min}} = \frac{5}{20} = 0.25 \text{ km/min} \]

**Step 2: Find the distance covered by Ravi in 100 minutes.**
- Now that we know Ravi covers 0.25 km in 1 minute, we can find out how much he covers in 100 minutes by multiplying the distance covered in 1 minute by 100.

\[ \text{Distance in 100 minutes} = 0.25 \text{ km/min} \times 100 \text{ min} = 25 \text{ km} \]

**Final Answer:**
- Therefore, the distance covered by Ravi in 100 minutes is **25 km**.
