Answer:
speed = 25 m/s
Explanation:
Driving at a speed of 90 km / hour . what is the speed in meters per seconds.
converting from km to meter one have to multiply by 1000. This means 1 km is equal to 1000 meter. Converting 90 km to meter we have to multiply 90 by 1000.
90 × 1000 = 90000 meters
The time is in hours so we have to convert to seconds as required by the question.
60 minutes = 1 hour
Therefore,
1 minutes = 60 seconds
60 minutes = 3600 seconds
This means 1 hour = 3600 seconds
speed = 90000/3600
speed = 25 m/s
