Hey there,
60 minutes = 7 miles
1 minute = 7 / 60
= 7/60
24 minutes = 7/60 x 24
=2.8 miles
Hope this helps :))

Slope of AB=(2-3)/(1+1)=-1/2; AC=(-1-3)/(-3+1)=-4/-2=2; BC=(-1-2)/(-3-1)=-3/-4=3/4.
The product of two sides that are perpendicular is -1. Slopes of AB and AC are perpendicular so angle A is a right angle. ABC is a right-angled triangle.
F(x) = 3x^3 -2x^2 - 19x -6
