Answer:
9.3
Step-by-step explanation:
if both travel at same speed they will take equal distance and time to reach the middle and collide.
hence, 27/2 =13.5km
speed=distance/time
time = distance/speed
time= 13.5/87 = 0.15517mm hr
0.15517×60 = 9.31minutes
<span>-3(6.3x + 7y - 2.5)
= -3(6.3x) -3(7y) - 3(-2.5)
= -10.8x - 21y + 7.5

The increasing order of the complex numbers is (√2 - i)⁶ < (√2 - √2i)⁸ = (√3 - i)⁶ = (-1 + √3i)¹² < (√3 - √3i)⁴.
<h3>
Absolute values of the complex numbers</h3>
The absolute values of the complex numbers are determined as follows;
(sqrt3-sqrt3i)^4 = (√3 - √3i)⁴
(-1+sqrt3i)^12 = (-1 + √3i)¹²
(sqrt 3-i)^6 = (√3 - i)⁶
(sqrt2-sqrt2i)^8 = (√2 - √2i)⁸
(sqrt2-i)^6 = (√2 - i)⁶
Increasing order of the complex numbers;
(√2 - i)⁶ < (√2 - √2i)⁸ = (√3 - i)⁶ = (-1 + √3i)¹² < (√3 - √3i)⁴.
