Tim found the distance between each of the 21 rungs in a 5-meter ladder using the equation 20d = 5. If Tim decides to make a ladder that is 10 meters long instead, what would the distance (d) between the rungs be?

Answer 1

0.10 meters

Since the original equation was 20d = 5, when the length of the ladder is doubled to 10 meters, the new equation would be 20d = 10. Solving for d, d = 10/20 = 0.5 meters. Then, to find the distance between the rungs in the 10-meter ladder, you divide 0.5 meters by 5, so the distance would be 0.10 meters.
