Deborah ran a 12-kilometer race. She completed the race in 1.6 hours. Deborah's speed for the first kilometer can be represented by the function d=7.3h, where d is distance in kilometers and h is time in hours. Was Deborah's average speed for the first kilometer of the race faster or slower than her average speed for the entire race? Faster
Slower
The Same

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
