Final answer:
To convert the car's speed from 90 km/h to m/s, divide by 3.6, resulting in a speed of 25 m/s.
Step-by-step explanation:
To convert the speed of a car from kilometers per hour (km/h) to meters per second (m/s), we use the conversion factor where 1 km/h is equivalent to approximately 0.27778 m/s. This conversion factor is derived from the fact that 1 km equals 1000 meters, and 1 hour equals 3600 seconds.
To convert 90 km/h to m/s:
Divide 90 by 3.6 (since 1 km/h = 1000 m / 3600 s = 0.27778 m/s)
90 km/h ÷ 3.6 = 25 m/s
To convert the speed from km/h to m/s, we can use the following conversion factor
1 km/h = 0.278 m/s
So, to find the speed of the car in m/s, we can multiply the speed in km/h by the conversion factor:
90 km/h * 0.278 m/s = 25.2 m/s
Therefore, the car traveling at 90 km/h is moving at 25 m/s.
