Answer 2

To calculate the speed (v) in both meters per second (m/s) and kilometers per hour (km/h), we can use the formula:

Speed (v) = Distance (s) / Time (T)

Given: T = 15 minutes = 15 minutes * (1 hour / 60 minutes) = 0.25 hours s = 4.5 kilometers

1. Calculate the speed in meters per second (m/s): Since 1 kilometer = 1000 meters, we need to convert the distance from kilometers to meters:

Distance (s) = 4.5 kilometers * 1000 meters/kilometer = 4500 meters

Now, use the formula to find the speed:

Speed (v) = Distance (s) / Time (T) v = 4500 meters / 0.25 hours v = 18000 meters/hour

2. Calculate the speed in kilometers per hour (km/h):

The speed is already given in meters per hour, but we can convert it to kilometers per hour:

Speed (v) = 18000 meters/hour * (1 kilometer / 1000 meters) v = 18 kilometers/hour

So, the speed is: v = 18000 meters/hour = 18 kilometers/hour.
