A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft)
20 30
50 75
80 120
120 ? Which statement correctly explains how to find the distance traveled after 120 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. 20 multiplied by 6 is 120, so you can multiply 30 times 6 to find the distance. 30 multiplied by 4 is 120, so you can multiply 20 times 4 to find the distance.
