Q. Kong took 15%15\% fewer seconds than Nolan took to complete his multiplication timed test. Kong took 8585 seconds. \newlineHow many seconds did Nolan take?\newline□\square seconds
  1. Set Up Equation: Kong took 15%15\% fewer seconds than Nolan, so let's call the time Nolan took as NN. We know that Kong's time is 85%85\% of Nolan's time because 100%−15%=85%100\% - 15\% = 85\%. So we can write the equation: 0.85N=850.85N = 85.
  2. Solve for N: To find N, we divide both sides of the equation by 0.850.85: N=850.85N = \frac{85}{0.85}.
  3. Calculate N: Now, let's do the calculation: N=850.85N = \frac{85}{0.85} gives us N=100N = 100.
  4. Final Answer: So, Nolan took 100100 seconds to complete his multiplication timed test.
