Answer:

speed = 25 m/s

Step-by-step 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
