Answer:
90 miles
Step-by-step explanation:
Let ori. speed = z
distance = speed × time
= z × 2
= 2z miles
distance = (z - 15) × 3
= (3z - 45)miles
2z = 3z - 45
z = 45mph
distance = 45 × 2
= 90 miles
distance = (45-15) × 3
= 90 miles

Answer:
i=0
Step-by-step explanation:
8(1+2i)-(7-3i)=1+5i
8+16i-7+3i=1+5i
1+19i=1+5i
1+19i-5i=1
1+14i=1
14i=1-1
14i=0
i=0/14
i=0
