A car completes a journey in 6 h with a speed of 50 km/h. At what speed must it travel to complete the journey in 5 h?

Options

A. 50 km/h
B. 60 km/h
C. 25 km/h
D. None of these

Answer

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

### Step 1: Calculate the distance traveled by the car in 6 hours.
- **Formula**: Distance = Speed × Time
- **Given**: Speed = 50 km/h, Time = 6 h
- **Calculation**:
\[ \text{Distance} = 50 \, \text{km/h} \times 6 \, \text{h} = 300 \, \text{km} \]

### Step 2: Determine the speed required to cover the same distance in 5 hours.
- **Formula**: Speed = Distance / Time
- **Given**: Distance = 300 km, Time = 5 h
- **Calculation**:
\[ \text{Speed} = \frac{300 \, \text{km}}{5 \, \text{h}} = 60 \, \text{km/h} \]

### Final Answer:
The speed required to complete the journey in 5 hours is **60 km/h**.
