A runner hopes to complete the 10,000-mm run in less than 30.0 minmin. After running at constant speed for exactly 27.0 minmin , there are still 1100 mm to go. The runner must then accelerate at 0.23 m/s2m/s2 for how many seconds in order to achieve the desired time? Express your answer using two significant figures.
