30 mph for 0.5 hrs = 15 miles
80 mph for 2 hours = 160 miles
160 +15 = 175 miles total
For x +iy absolute value = √(x² + y²)
Absolute value of -4-√2i = -4-i√2, comparing x = -4, y= -√2
<span>
Absolute value = </span>√( (-4)² + (-√2)²),
(-4)² = (-4)*(-4) = 16, (-√2)² = -√2 * -√2 = 2
<span>
= </span><span>√( (-4)² + (-√2)²)
</span><span>
</span>= √(16 + 4) = √20
√20 = √(4*5) = √4 * √5 = 2√5
Absolute value = <span>2√5</span>

Answer: 1 hour and 20 mins
Step-by-step explanation:
Lily has to walk 4 more miles to complete her goal and with the pace of 3m/h she will have to for 1 hour 20 mins, to complete her goal.
Distance to be covered= 4 miles Speed= 3 miles per hour
Time= Distance/Speed
Time= 4/3
Time= 1.33 hours
Time= 1 hour and 20 mins
