Here, the distance traveled is not given, but Irina's bike-riding speed is:  it is 16 mph.

Let the distance traveled be d.  Then d = (27 mph)(0.4 hr) = 10.8 miles.

By bicycle, distance = rate times time.  Here, 10.8 miles = (16 mph)(time), and so

                10.8 mi
time = --------------- = 0.675 hour (40.5 minutes).
             16 mph
