Answer:

40/10 [4 meters/sec]

Step-by-step explanation:

Watch for what the units are telling us. The number that is being requested

is speed in units of meters/sec. We are given 40 meters and 10 seconds. If we divide 40 meters by 10 seconds (10 meters/10 seconds), we get 4 meters/sec, the correct dimension.
