Select the correct answerA bus covers a distance of 216 km in 4 hours. What is the speed of bus in m/s?Options5 m/s15 m/s18 m/s20 m/s

To solve this problem, we need to follow these steps:

1. First, we need to convert the distance from kilometers to meters because the speed is asked in meters per second. We know that 1 kilometer is equal to 1000 meters. So, 216 kilometers is equal to 216 * 1000 = 216000 meters.

2. Next, we need to convert the time from hours to seconds because the speed is asked in meters per second. We know that 1 hour is equal to 3600 seconds. So, 4 hours is equal to 4 * 3600 = 14400 seconds.

3. Now, we can calculate the speed by dividing the distance by the time. So, the speed of the bus is 216000 meters / 14400 seconds = 15 meters per second.

So, the correct answer is 15 m/s.

To solve this problem, we first need to convert the distance from kilometers to meters and the time from hours to seconds because the speed is asked in meters per second (m/s).

1. Convert kilometers to meters: 216 km = 216,000 meters
2. Convert hours to seconds: 4 hours = 14,400 seconds

Now, we can calculate the speed by dividing the distance by the time.

Speed = Distance / Time Speed = 216,000 meters / 14,400 seconds = 15 m/s

So, the correct answer is 15 m/s.
