Web3 dec. 2024 · It is called indirect proof or Proof by Contraposition. Example – Prove that if n is an integer and 3n+2 is odd, then n is odd. Solution – The first step in a proof by contraposition is to assume that the conclusion of the conditional statement “If 3n+2 is odd, then n is odd.” is false; namely, assume that n is even. http://www.icoachmath.com/math_dictionary/indirect-proof.html

WebSolution: Consider speed as m and time parameter as n. If the time taken increases, then the speed decreases. This is an inverse proportional relation, hence m ∝ 1/n. Using the inverse proportion formula, m = k/ n. m × n = k. At speed of 60 miles/hour, time = 3 hours, from this we get, k = 60 × 3 = 180.
