The speed of a bus is 24 km/hr. How much distan

To find out how far the bus travels in 12 seconds, we first need to convert the speed from kilometers per hour to meters per second. The speed of the bus is 24 km/hr.

Conversion of Speed

To convert kilometers per hour to meters per second, we use the following formula:

• 1 km/hr = 1000 m / 3600 s

So, to convert 24 km/hr:

Speed in m/s = 24 * (1000 / 3600) = 6.67 m/s

Calculating Distance

Now, we can calculate the distance traveled in 12 seconds using the formula:

• Distance = Speed × Time

Substituting the values:

Distance = 6.67 m/s × 12 s = 80.04 m

Final Answer

Rounding this off, the bus will travel approximately 80 meters in 12 seconds. Therefore, the correct answer is D. 80 m.
