A high-speed elevator can rise 480 feet in 30 seconds. Which expression represents the rate, in feet per minute, of the elevator?

60 second is 1 minute

30*2=60

Now do:

480*2 = 960

480 (2) is the expression

Answer = 960 ft

When you post a question with a list of choices under it,

you're supposed to give us the choices too, not just the

question.

(480 ft) / (30 sec) x (60 sec/min) = 960 ft/min.
