<h2>Answer : Option A) 1 foot/second</h2><h3>Explanation :</h3>
If we consider that the plates are placed 2 ft apart and there has to be 1800 meals that needs to be delivered in an hour.
so if we multiply 2 ft and 1800 meals that is delivered in 1 hour,we get 2 X 1800 = 3600 meals in an hour.
If we try to accommodate the plates at each ft then there will be 3600 meals delivered in 1 hour.
we know that 1 hour has 3600 seconds in it.
So, here the distance is 1 ft, and speed has to be determined time is 1 hour = 3600 seconds
3600 meals / 3600 seconds = 1 foot per second.
OR 1800 meals set at 2 ft apart in 3600 seconds will give the speed of the belt as 1 foot per second.
(1 ft = speed X 1 hour)
<h2>so, the speed also will be 1 foot per second. </h2>
