Answer: 90 seconds or 1.5 minutesStep-by-step explanation: 2 minutes(120 seconds) divided by 4 edges equals 30 seconds per edge. To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 secondstimetaken tocrossfrom one corner toanotherdiagonally is 90secondsor 1.5 minutes.## What is an expression?
