Convert 57ft per hour to 57 ft per minute. how do i convert from ft per hr to ft per min?

Divide by 60 because it is hour to minutes. Just ignore the feet because it can confuse you. Since it is the same unit before and after the conversion, we dont have to do anything to it.
57 ft/hr⇒ 57 ft/min
ft and ft cancel
divide 60(hour to minutes)

Answer is 0.95 ft/min

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
