The speed of a bus is 72 km/hr. The distance covered by the bus in 5 seocnds is

Options

A. 100m
B. 60m
C. 50m
D. 74.5m

Answer

To find the distance covered by the bus in 5 seconds, we can follow these steps:

### Step 1: Convert the speed from km/hr to m/s
The speed of the bus is given as 72 km/hr. We need to convert this speed into meters per second (m/s) because the time is given in seconds.

**Conversion formula:**
1 km/hr = (1000 meters / 3600 seconds) = 1/3.6 m/s

So, to convert 72 km/hr to m/s:
\[ \text{Speed in m/s} = 72 \times \frac{1000}{3600} \]
\[ = 72 \times \frac{5}{18} \]
\[ = 20 \text{ m/s} \]

### Step 2: Calculate the distance covered in 5 seconds
Now that we have the speed in m/s, we can calculate the distance covered in 5 seconds using the formula:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
Substituting the values:
\[ \text{Distance} = 20 \text{ m/s} \times 5 \text{ s} \]
\[ = 100 \text{ meters} \]

### Final Answer
The distance covered by the bus in 5 seconds is **100 meters**.
