Superman needs to save Lois from the clutches of Lex Luthor. After flying for 8 seconds, he is 1748 meters from her. Then at 17 seconds he is 1352 meters from her. What is Superman's average rate? How far does Superman fly every 7 seconds? How close to Lois is Superman after 24 seconds

60: 45 =12: 9 =4: 3 so the answer is 4: 3

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.
