Ed stands on a moving walkway and gets from one end of the walkway to the other in 20 seconds. The walkway is 44 feet long. Which statements are true?
Every 8 seconds, Ed travels 32 feet.
Ed travels 11 feet every 5 seconds.
Ed travels 2.2 feet per second.
Ed travels 0.9 of a foot every 2 seconds.
Every 10 seconds, Ed travels 22 feet.
Answer: Ed travels 2.2 feet per second. Every 10 seconds, Ed travels 22 feet. Ed travels 11 feet every 5 seconds.
Explanation: Divid feet (44) by the seconds (20) to find out how far Ed can move in a second. 44 ÷ 20 = 2.2 Multiply the feet per second by the seconds in each option to see which is correct.
(I’ll go through them in order of how you listed them) 8 x 2.2 = 17,6 So first one is false 5 x 2.2 = 11 So it’s true 1 x 2.2 = 2.2 So it’s true 2 x 2.2 = 4.4 So it’s false 10 x 2.2 = 22 So it’s true
