A bug is traveling at a rate of 18 inches per minute. write the rate in feet per minute

(18 inch / 1 minute) x (1 foot / 12 inch)

= (18 x 1) / (1 x 12) (foot / minute)

= 18/12 foot/minute = 1.5 foot/minute

When traveling a certain distance, it is done at a certain speed (rate) for a certain length of time. The formula that ties these variables together is ... d = r · t

So 18 inches per minute is 1.5 feet per minute.
