Hi
I hope it helps :)
Step-by-step explanation:
To find the speed of the bus in km/hr, we need to follow these steps:
1. **Convert meters to kilometers**: Since 1 kilometer = 1000 meters, we can convert 200 meters to kilometers:
\[
\frac{200 \text{ meters}}{1000 \text{ meters/kilometer}} = 0.2 \text{ kilometers}
\]
2. **Convert seconds to hours**: There are 3600 seconds in an hour. Therefore, to convert 30 seconds to hours:
\[
\frac{30 \text{ seconds}}{3600 \text{ seconds/hour}} = \frac{1}{120} \text{ hours}
\]
3. **Calculate speed in km/hr**: Now that we have the distance in kilometers and the time in hours, we can calculate the speed:
\[
\text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{0.2 \text{ km}}{\frac{1}{120} \text{ hr}} = 0.2 \times 120 \text{ km/hr} = 24 \text{ km/hr}
\]
Therefore, the speed of the bus is \( \boxed{24} \) km/hr.
Concept :-
What is speed?
Speed is the rate of change of distance per unit time. It is a scalar quantity(has magnitude only; no direction)
Given that,
- Distance travelled by the bus = 200m
- Time taken to reach the distance = 30s
To find,
The speed of the bus
Solution :-
We know that,
⇒ Speed = Distance/time
⇒ Speed = 200m/30s
⇒ Speed = 6.67m/s
But we have to find the answer in km/hr,
Converting to km/hr,
⇒ 6.67m/s * 3600s/1000m
⇒ 24.012 km/hr.
