Answer: 20m per second

Explanation:

There are 1000 m in a km. This means that the bus is moving at a speed of 72000 m/hr.

There are 60 minutes in an hour. To find the speed per minute, you would divide both sides by 60.

(72000/60)m per (60/60)minute

1200 m per minute

There are 60 seconds in a minute. To find the speed per minute, you would divide both sides by 60.

(1200/60)m per (60/60)second

20m per second
