Answer:
Step-by-step explanation:
in tri ADC and tri BDC
∠ADC =∠BDC = 90
DC is common
AD = BD (given)
triangle ADC ≅ tri BDC by SAS congruency
hence AC = BC by CPCT ( congruent parts of congruent triangles)
hence, BC = 13
187/3 = 62.33/1
He drove an average of 62.33 mph
The reason it's not reasonable is because you would have to multiply smaller numbers to get that number when in fact the actual answer is 1364
