I think it is C.Skewed right.
<span>The distance to the school is: 27 miles/hour x (10/60) hours = 27(1/6) = 4.5 miles.
The time it will take her to get to school if she goes 40 miles/hours is: t = d/v = 4.5 miles/40 miles/hour = 0.1125 hour = 6.75 minutes. </span>
Given two points A(x₁,y₁) and B(x₂,y₂) the distance betwen these points will be:
dist(A,B)=√[(x₂-x₁)²+(y₂-y₁)²].
We have these points: A(0,0) and B(6,3); its distance will be:
dist(A,B)=√[(6-0)²+(3-0)²]
=√(6²+3²)
=√(36+9)
=√45 ≈ 6.71
Answer: D. 6.71 units.
