A car travels at a speed of 75 m/s. for 2 hours. What is the distance (in km) travelled by the car?

Options

A. 500
B. 525
C. 540
D. 550

Answer

To solve the problem of how far a car travels at a speed of 75 m/s for 2 hours, we can follow these steps:

### Step 1: Convert the speed from meters per second to kilometers per hour.
To convert meters per second (m/s) to kilometers per hour (km/h), we use the conversion factor:
\[ 1 \text{ m/s} = \frac{18}{5} \text{ km/h} \]
So, we calculate:
\[ 75 \text{ m/s} \times \frac{18}{5} = 270 \text{ km/h} \]

### Step 2: Calculate the distance traveled in 2 hours.
Using the formula for distance:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
We know the speed is 270 km/h and the time is 2 hours. Therefore:
\[ \text{Distance} = 270 \text{ km/h} \times 2 \text{ h} = 540 \text{ km} \]

### Final Answer:
The distance traveled by the car is **540 kilometers**.
