Question

A fly can walk around a cubical block in two minutes. How long will it take the fly to walk along the edges of the cube from one corner to the opposite corner if it walks at the same rate?

Answers

  1. Answer: 90 seconds or 1.5 minutes
    Step-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 seconds

  2. The time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.

    What is an expression?

    The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
    Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax’s operation order and other properties.
    Given that a fly can walk around a cubical block in two minutes.
    The time taken to cover all the one edge is,
    T = 120 / 4
    T = 30 seconds
    To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds. Mathematically written as,
    To = 3 x 30
    To = 90 seconds
    To = 1.5 minutes
    Therefore, the time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.
