Question

A car moves with a constant speed a distance 12.6 km in 15 min. what is the car’s speed in metres of per second heeeeelp!​

Answer 1

Ответ:

If it is a smooth motion, then the speed can be found by the formula (minutes turn into hours, 15 minutes = 0.25 hours):

12,6/0,25=50,4

Answer 2

To find the car's speed in meters per second (m/s), you need to convert both the distance and time into the appropriate units.

1. Distance: The car moves 12.6 kilometers.

2. Time: The car covers this distance in 15 minutes. To convert this to seconds, remember that 1 minute is equal to 60 seconds. So, 15 minutes = 15 x 60 = 900 seconds.

Now, you can calculate the speed in m/s using the formula:

Speed (m/s) = Distance (m) / Time (s)

First, convert the distance from kilometers to meters:

Distance (m) = 12.6 km * 1000 m/km = 12,600 meters

Now, you can calculate the speed:

Speed (m/s) = 12,600 meters / 900 seconds = 14 m/s

So, the car's speed is 14 meters per second.
