Cesar, Carlos, David, and Edwin decided to have a push-up contest. The following table describes the push-up speeds of the four boys. Which boy has the fastest speed?

Answer:
Edwin (55 push-ups per minute)
Step-by-step explanation:
We need to find the actual number of pushups per one minute in order to compare them on the same base (per ONE minute). So we do"
Cesar: 200 / 4 = 50 pu/min
Carlos: 240 / 5 = 48 pu/min
David: 150 / 3 = 50 pu/min
Edwin: 110 / 2 = 55 pu/min
Therefore, Edwin is the fastest since he does more pushups per minute.
