Amoving walkway at an airport moves at a piece of 1.75 ft./s. if you stand on the walkway as it moves how long will it take to transfer you to 280 feet

It says that a piece of one 1.75 ft./s. means 1.75x, and when it says, "how long will it take to transfer you to 280ft," its telling you to plug in 280 to 1.75 which is multiplying 1.75(280),

which the answer is: 490 seconds

Hope it helped :)
