Ответ:
we are given: the leatherback sea turtle has maximum speed = 21.92 miles per hour.
distance in miles is taken by d variable.
time in hours is taken by t variable.
we know formula for speed = distance /time.
therefore, we can write an inequality as
or
.
therefore, d/t < 21.92 is the equation that represents a speed that is less than that of the leatherback sea turtle. where d is distance in miles and t t is time in hours.
