Answer:
72 campers I think is the correct answer
-21/4
Step-by-step explanation:
slope = y2-y1/ x2-x1
-18 - 3 / 17-13 = -21/4
That point P(x,y)
x = (-2+10)/2 = 4
y = (3+3)/2 = 3
=> P (4,3)
14.4 m / s
=distance between the car
=0.8 × 9
=7.2m
=time taken
=0.5s
=speed
=distance/time
=7.2m/0.5s
=14.4 m / s
